Powder neutron diffraction, also carried out over a wide temperature range, establishes that the intermediate magnetic phase is incommensurate, and confirms that the lowest temperature phase has a linear antiferromagnetic structure with a (0 1 0) propagation vector. The respective transition (Néel) temperatures, in zero applied magnetic field are 34.0 and 28.0 K.Keywords: Antiferromagnetic materials; Intermetallics; Magnetization; Neutron diffraction; Specific heat; Vectors; Powder neutron diffraction; Propagation vector; Rare-earth ternary compounds; Terbium compounds Magnetism; Neutron diffraction; Rare-earth ternary compounds; Specific heat200610.1016/j.jmmm.2005.07.0122015-12-07
