Direct evidence for the magnetic ordering of Nd ions in NdMn${}_2$Si${}_2$ and NdMn${}_2$Ge${}_2$ by high resolution inelastic neutron scattering

Abstract

We have investigated the low energy nuclear spin excitations in NdMn${}_2$Si${}_2$ and NdMn${}_2$Ge${}_2$ by high resolution inelastic neutron scattering. Previous neutron diffraction investigations gave ambiguous results about Nd magnetic ordering at low temperatures. The present element-specific technique gave direct evidence for the magnetic ordering of Nd ions. We found considerable difference in the process of the Nd magnetic ordering at low temperature in NdMn${}_2$Si${}_2$ and NdMn${}_2$Ge${}_2$. Our results are consistent with those of magnetization and recent neutron diffraction measurements.
