The Rare Earth

For all the Rare-Earth (R) the R2In form in the same crystal structure (P63/mmc). These compounds show a great variety of magnetic behaviors. When the temperature decreases, the magnetic susceptibility of Er2InTb2In and Gd2In increases, passes through a maximum then decreases. For Gd2In this behavior was associated with change from a paramagnetic to a ferromagnetic then to an antiferromagnetic state. We have performed magnetic, transport (Tb, Er), Mössbauer spectroscopy (Er) and powder neutron diffraction experiments (Gd, Tb, Er) on these compounds. Unlike Gd2In the resistivity of Tb2In and Er2In does not reveal any anomaly at the temperature where the susceptibility begins to decrease and the Tb2In and Er2In magnetizations show the same behavior at all temperatures in the ordered region. Neutron diffraction experiments reveal ferromagnetic and antiferromagnetic structures at low temperature.

Increasing Temperature

The Tm2Fe17 compound has been studied by means of powder neutron diffraction. The compound undergoes a spin-reorientation transition (SRT) of the “easy axis – easy plane” type with increasing temperature from 75 K to 100 K. The SRT is accompanied by a distinct anomaly in the temperature dependencies of the Tm- and Fe-ion magnetizations, significative of large magnetization anisotropy. Using three sublattices model, the parameter of the Tm-Fe interaction and constants of magnetic anisotropy are determined.
