The magnetocaloric performance of La 0.67 Ca 0.27 Sr 0.06 Mn 1.05 O 3 is investigated as a function of the powder grain size and also as a function of decoration of grains with highly conductive silver particulates as a coating layer. We demonstrate

It is now well established that the paramagnetic-to-ferromagnetic transition in the magnetocaloric $\mathrm{La}{(\mathrm{FeSi})}_{13}$ is a cooperative effect involving spin, charge, and lattice degrees of freedom. However, the influence of this corr

In this paper, we present the results of an experimental investigation on the magnetocaloric properties of hydrogenated La(Fe-Mn-Si)13-H with Mn substituting Fe to finely tune the transition temperature. We measured the specific heat under magnetic f

We compare the magnetocaloric effect of samples prepared with different thermal conductivities to investigate the potential of composite materials. By applying the magnetic field under operating conditions we test the material's response and compare

Manganites are one of only a small number of material families currently being trialled as room temperature magnetic refrigerants. Here we examine the dependence of the thermal conductivity, K, of La0.67Ca0.33MnO3+/-{\delta} as a function of density,
