摘要：

Demagnetizing factors for disk samples of a commercial 80Ni permalloy have been measured using a vibrating sample magnetometer with fields provided by a Helmholtz coil pair. The range of values of m (diameter/thickness) is from 12.5 to 385. The experimental values of N are significantly higher than those calculated for an ellipsoid, but lower than those calculated assuming uniform magnetization.
