| Abstract: | The magnetization curves of gadolinium were measured with vibrating sample magnetometer, from which the formula M(H,T) was obtained using least square surface fitting. Then magnetic entropy changes can be calculated. These works are able to provide the preliminary information needed for the design of magnetic refrigerator. |
