摘要:The magnetic and magneto-transport properties of amorphous CoO1-vfilms have been systematically studied and manipulated by changing the concentration of oxygen vacancies. A giant exchange bias field HE≈ 4380 Oe and a large coercivity HC≈ 8500 Oe are observed at 5 K for the composite films. And, a metal to insulator transition has been demonstrated in CoO1-vfilms by decreasing the concentration of oxygen vacancies. Moreover, a remarkable decrease of the exchange bias and a slight increase of the saturation magnetization can be obtained by modifying the microstructures through post-thermal annealing.
