Magnetic transitions in CeCu0.86Ge2 and PrCu0.76Ge2 as studied by magnetocaloric effect - art. no. 052407

The results of heat capacity in the presence of an external magnetic field and resistivity measurements on the compounds CeCuxGe2 and PrCuyGe2 with th e starting x = 0.86 and y = 0.76 are reported. The magnetocaloric effect in the compounds was calculated from in-field heat-capacity data. The results clearly indicate the nature of magnetic transitions in both compounds and the metamagnetic transition with field in the cerium compounds, The observe d magnetocaloric effect is modest in spite of much smaller magnetic moment of Ce and Pr compared to heavy rare earths.
