Description
The magnetic ordering and crystal field interactions of the Pnma phases of both Tm2BaCoO5 and Tm2BaNiO5 are investigated by 169Tm Moessbauer spectroscopy and the temperature-dependent hyperfine interactions are compared with those obtained elsewhere for Tm2BaCuO5. The Pnma phases are shown to order magnetically at temperatures of 3.5(2) K (Tm2BaCoO5) and 4.85(5) K (Tm2BaNiO5), the order being induced by the transition metal. For Tm2BaNiO5 an additional first-order transition observed at T≤1.4 K is identified with the independent magnetic order of the thulium sub-lattice. (orig.)
