Influence of particle size on the magnetocaloric properties of Mn1.30Fe0.65P0.5Si0.5 powders.

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.

Theoretical description of the magnetocaloric effect in Mn-Fe-P-Si alloys.

We apply a thermodynamic model describing magnetoelastic effects and based on mean field theory to understand the physical origin of the first order ferro- to paramagnetic magnetostructural transition occurring in Mn1.3Fe0.65P0.5Si0.5. The phenomenological parameters of the model are determined through comparison with the entropy data measured by Peltier calorimetry under magnetic field. The values obtained support the idea that: the phase transition is driven by the strong magnetoelastic coupling present along the a lattice axis; the spin entropy plays a key role in the transition; the structural contribution has a minor counteracting role. Moreover, the number of magnetic moments derived from the model agrees with the picture describing the paramagnetic phase of the system as due to the disordered magnetic moments at the Mn sites only.

Ti substitution in MnBi rare-earth-free magnetocaloric compound.

The MnBi compound exhibits a first order magneto-structural phase transition around 630 K. This material could be suitable as a rare-earth-free magnetocaloric material provided that one can shift the transition temperature towards room temperature. In this work the effect of a partial substitution of Mn with Ti is investigated. In particular we study the transformation kinetics of the magneto-structural transition, in samples prepared with different techniques: powder metallurgy and rapid quenching from the melt. The samples show a logarithmic dependence of the transition temperature on the temperature scan rate upon cooling. This suggests that the transition occurs with the help of thermal fluctuations. The linear size of the activation volume v0 of these thermally activated processes is found to pass from 2.5 nm in MnBi to around 1.8 nm in Ti substituted samples.
