標題: | Superconductivity-induced magnetoresistance suppression in hybrid superconductor/magnetic tunnel junctions | 作者: | Chang, Yin-Ming Li, Kai-Shin Chiang, Wen-Chung Lin, Jiunn-Yuan MINN-TSONG LIN |

A suppression of tunneling magnetoresistance effect is observed as the Nb layer undergoes the superconducting transition. This suppression is thought to be due primarily to the coupling of the magnetic inhomogeneity of CoFe to the superconductivity of Nb. The magnetic structure-vortex interactions interplay each other, inducing a complex domain evolution in the magnetization process and consequently degrading the junction's antiparallel magnetization alignment. © 2009 The American Physical Society. |
