Proximity induced enhancement of the Curie temperature in hybrid spin injection devices.
نویسندگان
چکیده
We investigate the increase of the Curie temperature T(C) in a lateral spin injection geometry where the ferromagnetic (Ga,Mn)As injector and detector contacts are capped by a thin iron film. Because of interlayer coupling between Fe and (Ga,Mn)As T(C) gets enhanced by nearly 100% for the thinnest (Ga,Mn)As films. The use of the proximity effect might pave the way for practical implementation of spintronic devices.

Enhancement of superconductivity by decreased magnetic spin-flip scattering: Nonmonotonic TC dependence with enhanced magnetic ordering
Fe/Cu superlattices exhibit a structural and magnetic transition with increasing Fe layer thickness, thus increasing the Curie temperature. An enhancement in the superconducting transition temperature is found in proximity coupled Nb/@Fe/Cu# layers as the Fe thickness increases. These results indicate a weakening of the magnetic proximity effect for the material with higher Curie temperature, a...
متن کاملSpin Seebeck effect and spin Hall magnetoresistance at high temperatures for a Pt/yttrium iron garnet hybrid structure.
Based on unique experimental setups, the temperature dependences of the longitudinal spin Seebeck effect (LSSE) and spin Hall magnetoresistance (SMR) of the Pt/yttrium iron garnet (Pt/YIG) hybrid structure are determined in a wide temperature range up to the Curie temperature of YIG. From a theoretical analysis of the experimental relationship between the SMR and temperature, the spin mixing co...
متن کامل"Spin Injection and Scattering in Semiconductor Heterostructures"*
Efforts to implement semiconductor-based spintronic devices have been crippled by the lack of an efficient and practical means to electrically inject spin-polarized carriers into a semiconductor heterostructure. Spin injection from semimagnetic semiconductor contacts (ZnMnSe/AlGaAs/GaAs) has produced electron spin polarizations of ~ 85% in the GaAs QW [1]. Several factors potentially limit spin...

Conventional metallic magnets were the first choice for injecting spins into semiconductors in the past. Here...
متن کاملAntiferromagnetic proximity effect in epitaxial CoO/NiO/MgO(001) systems
Magnetic proximity effect between two magnetic layers is an important focus of research for discovering new physical properties of magnetic systems. Antiferromagnets (AFMs) are fundamental systems with magnetic ordering and promising candidate materials in the emerging field of antiferromagnetic spintronics. However, the magnetic proximity effect between antiferromagnetic bilayers is rarely stu...
