Magnetization study of a GdFe5Al7 single crystal
- 49 Downloads
A GdFe5Al7 single crystal with the tetragonal ThMn12-type structure has been studied in magnetic fields up to 14 T. The compound is ordered ferrimagnetically below T C = 262 K. Magnetization isotherms measured along the main crystallographic directions indicate that GdFe5Al7 displays easy-plane anisotropy. Anisotropy is also present within the basal plane between the  and  axes. The easy magnetization direction is the  axis with the spontaneous magnetic moment M s = 0.58 µ B /f.u. at T = 2 K.
