We investigate the spin Hall magnetoresistance (SMR) at room temperature in thin-film heterostructures of antiferromagnetic insulating (0001)-oriented α − Fe 2 O 3 (hematite) and Pt. We measure their longitudinal and transverse resistivities while rotating an applied magnetic field of up to 17 T in three orthogonal planes. Second-harmonic resistance ( R2ω) as a function of the magnetic field angle for a 4-nm α-Sn film. The data in ( A) were measured with a Hall bar whose length is along [11ˉ2] of the α-Sn film, while those in ( B) were measured with a Hall bar with its length along [1ˉ10]. OPEN IN VIEWER. 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 spin current related magnetoresistance, dubbed here as the anomalous Hall magnetoresistance, which has the same angular dependence as the recently discovered spin Hall.

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 model is used.

Magnetoresistance, giant magnetoresistance, and colossal magnetoresistance. The materials and mechanisms for these four types ofmagnetoresistance are distinctly different. A prerequisite for large θ SH is significant spin-orbit coupling. Of potential interest are compounds such as Ir 1−x Mn x, which are antiferromagnetic for various ranges of x.These compounds are widely used in spintronic devices because of the exchange bias fields that they imprint on neighboring ferromagnetic layers that lead to a unidirectional magnetic anisotropy ().

Along with extremely large and nonsaturating magnetoresistance (MR), ∼ 1.4 × 10 5 % at 2 K and 9 T, it shows strong anisotropy, depending on the direction of the magnetic field. Quantum oscillation and Hall effect measurements have revealed large hole and small electron Fermi pockets.

Large spin Hall magnetoresistance and its correlation to.

Therefore, the SSC is most important, and the three-spin correlation without SOC should dominate over the two-spin correlation with SOC. One another possibility for the large Hall response observed in MnGe films is the emergence of high-mobility carriers in the FM region, which can result in σ x y with a sharp peak structure, as typically. The spin-orbit interaction in heavy metal/ferromagnet/oxide structures has been extensively investigated because it can be employed in manipulation of the magnetization direction by in-plane current. This implies the existence of an inverse effect, in which the conductivity in such structures should depend on the magnetization orientation.

Sign reversal of magnetoresistance and inverse spin Hall effect in.

The magnetoresistance (MR) is the ratio of the electrical resistance of a material with and without an applied magnetic field [ 20 ]. In ferromagnetic conductors the MR is often dominated by effects that are not caused directly by the applied magnetic field, but rather by the magnetization orientation as controlled by the applied field.

For example Pt is known to have spin hall angle of 0.07 ~ 0.1 (7-10%). Ta is known to have spin hall angle of 0.12-0.15. It is important to find material with high spin hall angle for efficient magnetization switching [1] S. Cho, S.-h. C. Baek et al., 'Large spin Hall magnetoresistance and its correlation to the spin-orbit torque in W/CoFeb/MgO. One of the ways to access these properties in an ML in contact with an FM insulator is through its spin Hall magnetoresistance (SMR) [16, 22]. Another independent technique to probe the properties of the ML and the interface is the microwave driven spin-pumping SPE-ISHE. The spin Hall effect ( 1) allows electrical generation of spin current in materials with strong spin-orbit interaction (SOI) ( 2 ). The spin Hall angle, a material parameter that characterizes charge to spin conversion efficiency, scales with the longitudinal resistivity and the spin Hall conductivity ( 3 ).
