Abstract
We performed powder neutron diffraction experiments of Tb0.94Gd0.06B2C2 with transition temperatures at TO=14.2 K and TN=20.6 K in order to examine the magnetic structure in phase IV (T<TO) and phase AFM1 (TO<T<TN). 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 TO is an antiferro-octupolar (AFO) transition temperature.
