It is a ferrimagnet with exact compensation of the Ho and Fe sublattices at low temperatures, the spontaneous magnetic moment is zero at 4.2 K. At elevated temperatures, it passes through a wide maximum (4.2 mB at 200 K) and vanishes at TC = 315 K. The compound displays a high magnetic anisotropy of the easy-plane type with the [110] axis as the easy magnetization direction. The compound exhibits two field-induced magnetic phase transitions along the easy [110] axis and two more along the [100] axis, the hard direction in the basal plane. The critical fields of the lower- and higher-field transitions display qualitatively different temperature dependencies. A T-H magnetic phase diagram has been constructed for the [100] and [110] directions. Pracoviště Fyzikální ústav Kontakt Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Rok sběru 2016
