“…Thus, due to the decrease in R with decreasing temperature [see the gray solid curve in Fig. 4(a) measured for a reference single-crystal Fe layer directly grown on a semi-insulating (SI) GaAs ( 001) substrate], the AHE and PHE decrease with decreasing temperature [40]. Therefore, the strong temperature dependence of the EMF peak intensity at 094424-3 H = H r L can be attributed to these galvanomagnetic effects.…”

Topological crystalline insulator SnTe is a promising material for future spintronics applications because of the strong spin-orbit coupling and surface states protected by the mirror symmetry of the crystal. In this paper, using a high-quality epitaxial ( 001)-oriented Fe/SnTe/CdTe/ZnTe heterostructure grown on GaAs, we successfully observe the inverse spin Hall effect in SnTe induced by spin pumping, which is confirmed by detailed analyses of the dependence of the electromotive force on the microwave power, magnetic-field angle, and temperature. By a rough estimation, a relatively large spin Hall angle of ∼0.01 is obtained for bulk SnTe at room temperature. This large value may be partially caused by the surface states. Our result suggests that SnTe can be used for efficient spin-charge current conversion.

“…Consequently, M increases starting from M r . The increase of M leads to the increase of R PHE , as M is related to R PHE by the expression R PHE = kM 2 29–31 , where k is a material related coefficient. The maximum of M is the saturation magnetization M s .…”

The spin-orbit torque (SOT) effective fields, namely field-like and damping-like terms, depend on the thicknesses of heavy metal (HM) and ferromagnetic metal (FM) layers, in a stack comprising of HM/FM/HM or oxide. In this work, we report on the dependence of the SOT effective fields on the magnetization uniformity in the wires comprising of Ta/Co/Pt layer structure. SOT dependence on magnetization uniformity dependence was investigated by concurrent variation of the magnetization uniformity in Co layer and characterization of the SOT effective fields in each wire which excludes the layer thickness dependence influences. Our experimental results reveal that the field-like term decreases while the damping-like term increases with increasing Co magnetization uniformity. The magnetization uniformity influence on the effective fields is attributed to the spin Hall effect, which contributes to the SOT.

The resistivity anisotropy in ferromagnetic metals due t o spin-orbit interaction is considered with spin correlation taken into account. The obtained temperature dependence of AQ shows a round peak in accord with experiment. In the critical region d(Ae)/dt diverges as ( -t)l-(a+q) ( t = = ( T -Tc)/Tc, magnetic field h = 0), where pl is the cross-over exponent.L'anisotropie de la resistivite, causke par l'interaction spin-orbitale, dans les metaux ferromagnetiques est calculee en consid8rant aussi la correlation des spins atomiques. La dependence de An avec la temperature montre un pic arrond8, en accord avec les resultats Bxperimentaux.
