Özet

The magnetic properties of Ce 1-xTb xMn2Ge2 (0≤x≤1) were investigated by means of field-cooled and zero-field-cooled magnetization measurements in the temperature range 5K≤T≤600K. Earlier neutron diffraction experiments showed that Tb orders below 100 K while Ce does not order at any temperature. The substitution of Tb for Ce leads to a linear decrease in the lattice constants, and the magnetic interactions in the Mn sublattice cross over from a ferromagnetic character to an antiferromagnetic one. At low temperatures, the Tb sublattice also orders and reconfigures the ordering in the Mn sublattice. The results are collected in a phase diagram. © 2005 Elsevier B.V. All rights reserved.
