Measuring the effect of demagnetization in stacks of gadolinium plates using the magnetocaloric effect

► The magnetocaloric effect is used as an indirect measure of the internal magnetic field. ► To our knowledge nobody has published experimental determination of demagnetizing field in stack configurations of plates of magnetic material. ► We present good agreement between the experimental results and an established numerical model. ► This serves to show that the model may be used further to predict, e.g., optimal configurations.
