The isothermal magnetization of the compound has been calculated using this equation. The magnetic entropy change of the compound was determined from the surface area between the two adjacent isothermal magnetization curves divided by the average temperature. A comparison and an error analysis of the calculated magnetic entropy change and the one determined from the experimental data were given. %K bean-rodbell model %K magnetic state equation %K magnetocaloric effect %K MAGNETOCALORIC EFFECT %K MAGNETIZATION %K CALCULATION %K comparison %K error analysis %K experimental data %K magnetic entropy change %K surface area %K magnetization curves %K average %K temperature %K isothermal %K state equation %K compound %K Gibbs free energy %K volume %K based %K model
