High-resolution alternating-field technique to determine the magnetocaloric effect of metals down to very low temperatures

Yoshi Tokiwa, Philipp Gegenwart

The magnetocaloric effect or "magnetic Grüneisen ratio" ${\Gamma }_H=T^{-1}(dT/dH{)}_S$ quantifies the cooling or heating of a material when an applied magnetic field is changed under adiaba…
