Magnetic properties and magnetocaloric effects in ferrimagnetic compounds

Magnetic properties and magnetocaloric effects were studied in (GdxY1−x)3Co11B4 ferrimagnetic compounds. Rather high values of the entropy changes were shown in large temperature ranges. The ΔS values were correlated with high temperature dependences of resultant magnetizations determined mainly by the gadolinium sublattice one. Large relative cooling power was also shown.
