Calculation of Magnetic Entropy Changes of Gadolinium from Magnetization Curves

- Summary
- Metrics

Abstract

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