Ferromagnetism and giant magnetoresistance in zinc-blende FeAs.
The spin currents injected into the F layer and SOTs may be examined by electric measurements through its magnetoresistance and the anomalous Hall effect AHE. 40 The change of the resistance of the hybrid structure caused by the above effects is referred to as spin Hall magnetoresistance SMR. Local moments to induce the canonical spin-glass phase in the metallic region of Ti1xVx2O3. 8-10 In this paper, we report that the doped VBS Ti1xVx2O3 shows a large negative magnetoresistance and a heavy-mass elec-tron state likely caused by the polaronic coupling to the dimeric distortion. The ferromagnetic exchange interac. Here we experimentally demonstrate that the spin accumulation, subsequent spin backflow, and spin-charge conversion can give rise to a different type of spin current related magnetoresistance, dubbed here as the anomalous Hall magnetoresistance, which has the same angular dependence as the recently discovered spin Hall magnetoresistance.

Role of interface quality for the spin Hall magnetoresistance in nickel.
The spin Hall e ect SHE allows generation of spin current transverse to the current ow direction[14]. It was rst experimentally found in semiconductors [5] and later in paramagnetic heavy metals e.g. Pt, W[6, 7], where the e ect is typically larger in the latter than the former. The large spin current can di use into adjacent. In this work, we show that a strong MPE from the neighbouring Ga,FeSb layer induces giant proximity magnetoresistance PMR approximately 80 at 14 T and a large spin-splitting energy E.
Spin Hall magnetoresistance in paramagnetic NdGaO3.
The spin Hall effect is of current interest from a fundamental and a device application point of view. Most importantly, the spin Hall effect allows to transfer an electrical charge current into a pure spin current, i.e. a current carrying only spin angular momentum without an accompanying charge current.
Quantifying spin for future spintronics.
We investigate the spin Hall magnetoresistance in thin-film bilayer heterostructures of the heavy metal Pt and the antiferromagnetic insulator NiO. While rotating an external magnetic field in the easy plane of NiO, we record the longitudinal and the transverse resistivity of the Pt layer and observe an amplitude modulation consistent with the spin Hall magnetoresistance. In comparison to Pt. Spin current represents a flow of spin angular momentum carried by electrons. The spin Hall effect allows electrical generation of spin current in materials with strong spin-orbit interaction SOI .The spin Hall angle, a material parameter that characterizes charge to spin conversion efficiency, scales with the longitudinal resistivity and the spin Hall conductivity .

The force on a current-carrying wire in a perpendicular magnetic field is due to the force on the charge carriers moving through the wire. 12. This force on the charge carriers produces an increased resistance as the charge carriers collide more with atoms in the wire. This phenomenon is called magnetoresistance.

Large spin Hall magnetoresistance and its correlation to the spin-orbit torque in W/CoFeB/MgO Available via license: CC BY 4.0. Introduction. Spin-orbit coupling SOC 1, 2 is one of the most important phenomena in condensed matter physics, providing a mechanism to couple charge and spin of electrons, and bring several fields such like quantum spin Hall effect 3 - 5 and Topological insulators 6 - 9.Particularly, the most noticeable example for SOC-related phenomena is the spin Hall effect SHE 10 - 15, which has. The spin-dependent transport properties of magnetic materials are the basis of spintronics devices used, for example, for magnetic sensing and data storage [1].The electrical conductance of a magnetic device usually depends on its magnetization configuration, resulting in so-called magnetoresistance MR effects. Among these effects,.

The phenomena based on spin-orbit interaction in heavy metal/ferromagnet/oxide structures have been investigated extensively due to their applicability to the manipulation of the magnetization direction via the in-plane current. This implies the existence of an inverse effect, in which the conductivity in such structures should depend on the magnetization orientation. In this work, we report a.

Interconversion between charge and spin through spin-orbit coupling lies at the heart of condensed-matter physics. In normal metal/ferromagnet bilayers, a concerted action of the interconversions, the spin Hall effect and its inverse effect of normal metals, results in spin Hall magnetoresistance, whose sign is always positive regardless of the sign of spin Hall conductivity of normal metals.
Spin Hall magnetoresistance effect from a disordered interface.
ABSTRACT. We have studied the spin Hall magnetoresistance SMR, the magnetoresistance within the plane transverse to the current flow, of Pt/Co bilayers. We find that the SMR increases with increasing Co thickness: the effective spin Hall angle for bilayers with thick Co exceeds the reported values of Pt when a conventional drift-diffusion. Here we report that the spin Hall magnetoresistance of Ta/NiFe bilayers is negative, necessitating an additional interconversion process. Our theory shows that the interconversion owing to. In this work, we report a systematic study of the magnetoresistance MR of the W/CoFeB/MgO structures and its correlation to the current-induced torque to the magnetization. We observe that the MR is independent of the angle between magnetization and current direction, but is determined by the relative magnetization orientation with respect to the spin direction.

Magnetoresistance, giant magnetoresistance, and colossal magnetoresistance. The materials and mechanisms for these four types ofmagnetoresistance are distinctly different. 1. Ordinary Magnetoresistance OMR Fornon-magneticmetals, MReffects at low fields are very small, although the effect can become quite large for high fields. Interest in nonsaturating very large MR has exploded following the discovery of topological semimetals. These materials are regularly reported to exhibit record-high nonsaturating MR, known as extreme magnetoresistance XMR, with unusually high mobilities for bulk systems 12-18 and relatively low residual resistivity 0.The proximity of the chemical potential to the charge neutrality.
