The effect of magnetic domains on measurements of the magnetocaloric effect.
Number: 1570
Author(s) : BAHL C. R. H., SMITH A., NIELSEN K. K.
Summary
We discuss how magnetic domains influence the magnetic entropy change calculated from magnetisation data. In a simple qualitative model we show that the effect is to change the shape of the apparent isothermal entropy change curve compared to the true curve determined by the entropy. We further show that failure to correct for the magnetostatic demagnetisation will augment the apparent effect of domains.
