Specific heat and magnetocaloric effect in UNiGa [PDF]
Physica B: Condensed Matter, 1993 Abstract Temperature dependence of the specific heat was measured on a single crystal of UNiGa in magnetic fields. The value γ =40.9 mJ/mol K 2 does not change with the field-induced transition. The magnetic entropy is larger in the high-field (ferromagnetic) state (0.55× R In2) than in the AF ground state (0.50× R In2).

Self‐Cooling Molecular Spin Qudits
Advanced Materials, EarlyView.A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Magnetocaloric studies of the peak effect in Nb [PDF]
Physical Review B, 2007 We report a magnetocaloric study of the peak effect and Bragg glass transition in a Nb single crystal. The thermomagnetic effects due to vortex flow into and out of the sample are measured. The magnetocaloric signature of the peak effect anomaly is identified.
