Abstract
The differential magnetic susceptibility of intermetallic compounds RMn2Ge2 (R = Gd, Tb, Dy, Ho, Y) with a layered tetragonal structure is measured in pulsed magnetic fields up to 130 T. It is found that all these compounds u ndergo a first-order magnetic phase transition in strong magnetic fields. T he nature of this transition is discussed, and it is found that a change in the magnetic state of the manganese sublattice is responsible for the tran sition. (C) 2001 MAIK "Nauka/Interperiodica".
