Superparamagnetism in MgO-based magnetic tunnel junctions with a thin pinned ferromagnetic electrode
Jiafeng Feng,Jiafeng Feng,Junyang Chen,Junyang Chen,Munuswamy Venkatesan,G. Feng,Xiufeng Han,J. M. D. Coey +7 more
TL;DR: In this article, an inverted tunneling magnetoresistance is observed due to the unbalanced synthetic antiferromagnetic CoFe/Ru/CoFeB stack, and an abnormal temperature dependence of the junction resistance is associated with superparamagnetism when the thermal fluctuation energy exceeds the magnetic anisotropy energy.
