Abstract
The magnetization curves of gadolinium were measured with a vibrating sampl e magnetometer, from which the function M(H, T) was obtained using two-step least square fitting. Then magnetic entropy changes can be calculated. The se works can provide the perliminary information needed for the design of m agnetic refrigerator.
