Abstract
In previous investigations, it was shown that the compound ErMn 6Sn 6, that crystallizes in the HfFe 6Ge 6-type of structure, orders in a helimagnetic state at T N = 352 K, with the moments rotating within the [0 0 1] plane. In the helimagnetic state, metamagnetic behavior is observed, the critical field increasing when the temperature decreases from T N to 220 K and then decreasing with further decrease of the temperature from 200 to 75 K. At this latter temperature, the compound orders ferrimagnetically with the moments in the [0 0 1] plane. Very peculiarly, the in-plane magnetocrystalline anisotropy was found to decrease with temperature decreasing from 125 to 4.2 K. The magnetization of ErMn 6Sn 6 single crystals has been measured in magnetic fields up to 51 T. The measurements were performed at 4.2 K in the ferrimagnetic state and at 125 K in the helimagnetic state with the magnetic field applied along the three principal crystallographic directions. The measured magnetic isotherms are discussed in terms of the competition between the Er-Mn exchange interaction and the magnetocrystalline anisotropies of the Er and the Mn magnetic sublattice.
