研究了分别沉积在(001)MgO和(001)MgAl 2 O 4衬底上的CoFe 2 O 4/Pt异质结的自旋霍尔磁电阻效应。结果表明,在5 ~ 300 K的整个温度范围内,两种薄膜均存在界面非共线磁结构,但在低温下主要控制自旋输运性质.此外,自旋输运具有由不同衬底引起的外延应变修改特性,这已被研究的磁性曲线,SMR,各向异性磁电阻,和霍尔效应测量。
We have investigated the spin Hall magnetoresistance (SMR) in CoFe2O4/Pt heterostructures deposited on (001) MgO and (001) MgAl2O4 substrates, respectively. It is found that the interface non-collinear magnetic configurations should exist in both of the two films in the whole temperature range from 5 to 300 K but mainly dominate the spin transport properties at low temperature. Furthermore, the spin transport has featured epitaxial-strain-modified characteristics induced by different substrates, which has been investigated by magnetic curves, SMR, anisotropic magnetoresistance, and Hall effect measurements.
