摘要：

In this paper, we report the electric and magnetic effects after inserting Fe nanoparticles into the MgO layer of a Ta(25)/Co20Fe60B20(1.3)/MgO(1)/Fe(x)/MgO(1)/Co40Fe40B20(2.2)/Ta(5) structure. The samples were annealed at 300 degrees C without external magnetic field. Temperature dependence of resistivity and the anomalous Hall effect were used to infer the morphology of the Fe layer. With the addition of Fe nanoparticles, the optimal tunnel magnetoresistance ratio can be increased by up to 111.2%.
