Abstract

Magnetic properties of CeFeSi-type NdMn\(_{1-x}\)Ti\(_{x}\)Ge compounds studied by magnetization and magnetocaloric measurements are reported. The increase in Ti content leads to the essential increase in magnetic ordering temperature of the Nd sublattice and the magnetocaloric effect. The results are compared with those obtained on isotypic RTX compounds and discussed assuming the itinerant character of magnetism of these compounds.
