Tunable Spin Hall Magnetoresistance in All-Antiferromagnetic Heterostructures
文献摘要：
We investigate the spin Hall magnetoresistance(SMR)in all-antiferromagnetic heterostructures α-Fe2O3/Cr2O3 with Pt contacts.When the temperature is ultralow(＜50 K),the spin current generated in the Pt layer cannot be transmitted through Cr2O3(t=4nm),and the SMR is near zero.Meanwhile,when the temperature is higher than the spin fluctuation temperature TF(≈50K)of Cr2O3 and lower than its Néel temperature TN(≈300K),the spin current goes through the Cr2O3 layer and is reflected at the α-Fe2O3/Cr2O3 interface;an antiferromagnetic(negative)SMR is observed.As temperature increases higher than TN,paramagnetic(positive)SMR mainly arises from the spin current reflection at the Cr2O3/Pt interface.The transition temperatures from negative to positive SMR are enhanced with increasing Cr2O3 layer thickness,accompanied by the absence of SMR signals when t=10 nm.Such a tunable SMR builds a bridge between spin transport and structures.It also enriches antiferromagnetic spintronics.
