Temperature dependence of the lattice parameters and magnetic properties of Er3Ir single crystals

Abstract Er 3 Ir single crystals were grown by the Czochralski method from a levitated melt. The electrical resistivity thermal dependence exhibits ordering temperature of the erbium sublattice at 40 K and a spin reorientation process at 22 K. The DC and AC magnetic susceptibility show antiferromagnetic ordering in the form of an asymmetric peak. The magnetization in strong magnetic fields up to 140 kOe exhibits anisotropy. The lattice parameters’ thermal dependence of Er 3 Ir and Er 3 Ni show anisotropy and anomalous behaviour.
