Differential Scanning Calorimeter in Magnetic Field:
This magnetic DSC, based on thermoelectric modules, is able to measure the absolute specific heat with a relative error less than 3% and the latent heat of first order transformations. It works in vacuum (10-5mbar), in a temperature range between 250 K and 420K and in a magnetic field up to 1.85 T.
Adiabatic temperature variation probe:
A dedicated probe, based on a Cernox temperature sensor, permits the direct measure of the temperature change in a magnetic sample due to the variation of an applied magnetic field (up to 1.9T).

Non-contact probes have been also developed for the fast measurement of the adiabatic temperature change, even under pulsed magnetic field. For more details: F. Cugini, et al., Rev. Sci. Instrum. 85 (2014) 074902; F. Cugini, et al., Appl. Phys. Lett. 108 (2016) 012407.
Simulation of thermomagnetic (Brayton) cycles:
Through a special experimental setup, it is also possible to study the properties of materials during the repetition of thermomagnetic cycles, thanks to a pneumatic piston, which move the sample between two regions with different temperatures and magnetic field values.
