Effect of Tb and Al substitution within the rare earth and cobalt sublattices on magnetothermal properties of Dy0.5Ho0.5Co2

Popis výsledku v původním jazyce

The effect of Tb and Al substitution within the rare earth and cobalt sublattices on structural and magnetothermal properties of Dy0.5Ho0.5Co2 was studied. Multicomponent Laves phase alloys Tbx(Dy0.5Ho0.5)1−xCo2−yAly (x = 0, 0.3, 0.4, 0.5, y = 0, 0.25) synthesized using high-purity metals were studied using XRD, heat capacity and magnetocaloric measurements. Dy0.5Ho0.5Co2 has a first order phase transition at the Curie temperature TC = 110 K. Both Tb and Al substitution increase the TC. The increasing Tb content decreases slightly the MCE and all the transitions near the Curie temperature are of the first order. As for the Al-containing compounds, MCE measurements show that the phase transition type changes from the first to the second-order. The advantage of Al-containing compounds is a ‘table-like’ behavior of MCE.
