Magnetic structure of TbFe3

Abstract
The magnetic structure of TbFe3 was determined at room temperature and 77 K by powder neutron diffraction. The magnetic structure is essentially that of HoFe3, a colinear ferrimagnetic structure with the Tb moments coupled antiparallel to those of Fe in the basal plane. The three non‐equivalent crystallographic Fe sites exhibit different magnetic moments. On the basis of the neutron diffraction data collected above the ordering temperature, it is concluded that no substitution of Tb by Fe occurs.
