释义 | magnetocaloric effect A reversible change of temperature resulting from a change in the magnetization of a ferromagnetic or paramagnetic substance (see magnetism). The change in temperature ΔT, accompanying an adiabatic change of magnetic field ΔH, is: ΔT/ΔH = -T/CH(∂M/∂T)H CH is the specific heat capacity per unit volume at constant H and M is the magnetization |
