当测量直接重写磁光记录薄膜的矫顽力,饱和磁化强度所需的外磁场和磁化强度超出了所用VSM的测量范围时,若不采用增加膜厚的方法,则无法直接测量薄膜的基本参数.本文提出一种简单、有效、可靠、精密的外推方法间接地测量出它的磁性参数,并得到它的完整的温度特性,为每层膜居里温度的估计提供可靠的依据.

If the coercivity of magnetic material and the applied field for saturation magnetizing is so high that they are out of the range or near to the limit of measurement of VSM, basic magnetic parameters and hysteresis curves in saturation can not be measured directly． This paper presents extrapolation techniques for indirect measurement of basic magnetic parameters and hysteresis curves．
