Description

The sample of Ho2Fe9Ga4Al4 is prepared and the Curie temperature of sample is 166 K. The crystallographic and magnetic structure of sample was studied by powder neutron diffraction at 50 K and 300 K. The atom fractional occupancies of gallium and aluminum and the atom magnetic moments of Ho and Fe are obtained by Rietveld analysis program. The magnetic structure of sample at 50 K shows easy-axis anisotropy
