Magnetic properties of AgLnSe2 compounds (Ln=Ho, Er, Tm and Yb)

2001

Abstract The heavy lanthanide selenides AgLnSe2 (Ln=Ho–Yb) crystallize in the orthorhombic AgErSe2 type structure (P212121). The lanthanide ions are placed in the centres of slightly distorted octahedra, whereas each of the silver ions is surrounded by four selenide ions forming a strongly distorted tetrahedron. The high field magnetization (up to 14 T) and the magnetic susceptibility were measured on the polycrystalline samples. The crystal field parameters were estimated from the field dependences of the magnetizations, assuming a rhombic distortion of LnSe6 octahedra. The magnetic susceptibilities were also calculated using the same set of the crystal field parameters. None of the compou…

Crystal field effects and magnetic properties of Dy2Te3

1995

Abstract Magnetic susceptibility and magnetization measurements are presented for Dy 2 Te 3 . By means of crystal field calculations the energy levels of ground state and crystal field potentials for Dy 3+ ions have been evaluated taking the exchange interactions into account.
