| dc.description.abstractEn | The magnetic properties and the magnetocaloric effect are presented for the perovskite-related oxide SrFe<sub>0.5</sub>Co<sub>0.5</sub>O<sub>3</sub> prepared using electrochemical oxidation. SrFe<sub>0.5</sub>Co<sub>0.5</sub>O<sub>3</sub> exhibits a second order paramagnetic-ferromagnetic transition close to room temperature (<i>T</i><sub><i>C</i></sub>=330 K). The maximal magnetic entropy change Δ<i>S</i><sub><i>M</i></sub><sup><i>Max</i></sup> , the maximal adiabatic temperature change Δ<i>T</i><sub><i>ad</i></sub> and the refrigerant capacity are found to be equal to respectively 4.0 J/kgK, 1.8 K and 258 J/kg while raising the B-field change from 0 to 5 T. | |
