【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。更多还原

【Abstract】 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^0.90for 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 Ω have variety.This variety will be researched in future.更多还原
