WebApr 13, 2024 · Taking into account the contribution of anisotropic magnetoresistance the spin current was estimated as 1/3 of the total response. We show that both real and imaginary parts of spin mixing conductance are valuable for heterostructures with spin-orbit interaction in SrIr O 3. The spin Hall magnetoresistance of the heterostructure was … WebThe framework of this PSC-themed review is organized as follows: We first elucidate the basic concept of pure spin current, by afterwards of physical generation regimes and detection methods. Then pioneering exploration examples of PSC in the organic materials were demonstrated, including semiconductors and molecular magnets.

WebAug 11, 2016 · Spin currents are generally probed using measurements of the effects they produce in the metals through which they flow. They can, for instance, create a voltage drop perpendicular to the direction of the spin current or a torque that turns the magnetization direction of a magnetic film. However, these indirect measurements are often ambiguous ... WebSpin current is a flow of spin angular momentum carried by conduction electrons in normal and ferromagnetic metals or by spin waves (magnons) in ferromagnets [ 4 ]. Spin angular momentum transfer plays a central role both in magnetization switching caused by spin-transfer torque and in spin pumping caused by magnetization precession.
