Direct measurement of the magnetocaloric effect in cementite

Measurements of the magnetocaloric effect of cementite at its Curie temperature of 475K are presented. An adiabatic temperature change of 1.76±0.01K was measured using a direct measurement technique. The isothermal entropy change was determined from measurements of magnetisation isotherms and was sh...
