资源简介：
We present the results of an experimental investigation on the magnetocaloric properties of Mn1.30Fe0.65P0.5Si0.5 powders with different average particle sizes. Specific heat capacity under magnetic field cp(H,T) and magnetic field induced isothermal entropy change Δsiso(H,T) were measured by Peltier calorimetry. Thermal hysteresis is found to decreases with the particle size, but the refrigerant performance, evaluated by using the product Δsiso ΔTad of the isothermal entropy change Δsiso and the adiabatic temperature change ΔTad , has only slight dependence on the particle size.
