Magnetic tunnel junctions (MTJs), as the seminal spintronic devices, are expected for applications in magnetoresistive sensors due to their large magnetoresistance (MR) and high field sensitivity. Two hybrid Co/insulator/ZnO:Co junctions were fabricated with two different barriers to investigate the magneto-transport properties. Experimental results indicate that, both Co/MgO/ZnO:Co and Co/ZnO/ZnO:Co junctions show the positive and nearly linear MR, and their tunnel magnetoresistances (TMR) are… CONTINUE READING
