Abstract

We performed powder neutron diffraction experiments of Tb_0.94Gd_0.06B₂C₂ with transition temperatures at T_O=14.2 K and T_N=20.6 K in order to examine the magnetic structure in phase IV (T<T_O) and phase AFM1 (T_O<T<T_N). The experiments reveal that phase IV has an (1 0 frac(1, 2))-type antiferromagnetic (AFM) structure where the magnetic moments are aligned antiferromagnetically along the tetragonal c-axis, while phase AFM1 has an (1 0 0)-type AFM structure where the magnetic moments are aligned ferromagnetically along the c-axis. These results support our previous proposition that T_O is an antiferro-octupolar (AFO) transition temperature.
