Magnetocaloric effect

The magnetocaloric effect is measured directly by a differential copper – constantan thermocouple, having one junction “sandwiched” within the sample, and another one fixed nearby, and exposed to the same conditions as the sample [1].

 Magnetocaloric effect - temperature range

The temperature range with the current thermocouples is 80 – 360 K. The technique is best suited for magnets A, B, and E.

Measurement example: mangetocaloric effect of Mn3GaC [2].
