Magnetocaloric and Magnetoelastic Properties of the Gd_5Si_2Ge_2 with Small Indium Substitutions in p-sublattice

摘要

The purpose of this work was the complex investigation of magnetic, magnetocaloric and magnetoelastic properties of compounds based on Gd_5Si_2Ge_2 with small In substitutions in psublattice. The conducted measurements revealed that both the magnetocaloric effect and the volume magnetostriction upon cooling reach the higher values than upon heating. Indium substitution leads to the appearance of the second maximum on the temperature dependence of the magnetocaloric effect resulting in the increase of the refrigerant capacity.
