Article Preview

A single crystal of HoFe5Al7 (tetragonal ThMn12 structure) has been studied. HoFe5Al7 orders ferrimagnetically at TC = 227 K and has a compensation of the Ho and Fe sublattices at Tcomp = 65 K. The compound exhibits high easy-plane anisotropy. Strong anisotropy is also present within the basal plane, with the [110] axis being the easy magnetization direction. A high coercivity with Hc values attaining 1.6 T is found at 2 K. In the temperature range 40-80 K, HoFe5Al7 displays a field-induced magnetic transition along the easy [110] direction. Temperature dependence of the critical field Hcr of the transition is very strong, Hcr exceeds 14 T below 40 K.
