Persistent values of magnetocaloric effect in the multicomponent Laves phase compounds with varied composition

Popis výsledku v původním jazyce

We investigate the magnetocaloric effect (MCE) in the multicomponent RCo2-type compounds with a Laves phase structure varied by substitutions within both the rare earth (R) and Co sublattices. Complex substitutions increase the Curie temperatures (TC) at which the maximum MCE is observed. The Tbx(Dy0.5Ho0.5)1-xCo2 (0 ≤ x ≤ 0.5) compounds have transitions of the first order at the TC and exhibit a large magnetocaloric effect (adiabatic temperature change) ΔTad which decreases from 3.6 to 2.2 K (at μ0ΔH = 1.8 T) as x varies between 0 and 0.5. At the increasing Tb concentrations x above 0.5, the transition at TC in the compounds changes order from first to the second while MCE remains constant ∼2.2 K. Volume magnetostriction is of the order of 1000 ppm in the vicinity of TC.n
