摘要
研究了多晶Co薄膜制备态与退火态的磁滞回线与标度行为,结果表明:对易轴方向A∝A0+H(0.67-1.00)Ω0.90,对难轴方向A∝A0+H(1.75-2.50)Ω(1.45-0.95),与理论计算(α=0.95,β=0.28(Heisenberg模型))作比较,A与H的关系符合的较好,A与Ω的指数关系有些差异,这种差异还有待进一步研究。
The behavior of hysteresis scaling on thin polycrystalline Co film before and after annealing is studied. The results are A∝A0＋H^（0.67-1.00）Ω^0.90 for easy direction and A∝A0＋H^（1.75-2.50）Ω^（1.45-0.95） for difficult direction. The consistence between them is found and compared with those from theory calculation （ （ α = 0.95, β = 0.28 （ Heisenberg Model） ） ： A and H is well, A and have variety. This variety will be researched in future.
