Abstract

Lattice constants of polycrystalline UMn₂Si₂ and UMn₂Ge₂ samples were measured in the temperature range 80-300 K using the X-ray diffraction method. The anomalous behaviour of the lattice constant and the expansion coefficient, a, of UMn₂Ge₂ was observed at 150 K. The magnetostriction contribution of uranium sublattice is responsible for these anomalies.
