“…The magnitude of the Zeeman splitting depends on the g-factors of the electronic levels connected by the optical transition. The g-factors, being crystal field dependent, are quite different for rare earth ions in different sites [11,12]. Thus, the satellite lines due to ions in different sites should split differently under an external magnetic field.…”

Optical Zeeman effect measurements are performed at liquid helium temperature on Nd3+ ions in weakly doped YVO4 crystals in the range 11 350-11 390 cm-1 of the 4F3/2→ 4I9/2 neodymium transitions. This study provides confirmation that the concentration dependent satellite lines accompanying the optical transitions are due to ferromagnetically coupled pairs of Nd3+ ions in undistorted Y3+ sites of D2d point site symmetry. Nonlinear Zeeman splittings are observed in the range of experimental magnetic fields. These splittings are compared with those simulated from crystal field calculations by introducing the Zeeman Hamiltonian into the secular determinant before diagonalization. A reasonably good agreement between the calculated and experimental g-values is obtained, confirming that the exchange coupled neodymium pairs experience no crystal field perturbations.

“…Ainsi, nous avons niontre [l] que pour BaF,:RE3+ (RE = Nd, Pr, Sm, Tb, Dy, Ho, Er), la position des pics d'absorption IR Qtait pratiquement independante de l'ion RE3+ : 75 cm-l, 131 cm-l et 156 cm-1. Les raies particulieres sont interpretees comme des transitions Blectroniques entre sous-niveaux du niveau fondamental de la terre rare [2].…”

I n the BaF,: Dy3+ FIR spectrum the vibration frequencies of the interstitial compensation ion Fi is observed and the presence of some cluster types is revealed for concentrations equal t o or higher than 0.4 molyo. A 125 cm-l line is observed for the first time with Df+. I n BaF,:Nd3+ and BaF2:Ho3+ studies it is previously ascribed to the Fi vibration longitudinal mode in a trigonal site. Calculation gives 135 cm-l for the transversal mode vibration; experimentally it is observed for the first time. The 42 cm-l line previously ascribed to an electronic transition of Dy3+ in trigonal site disappears when the concentration increases.Le spectre infrarouge lointain de BaF2:Dy3+ permet d'observer les frbquences de vibration de ion de compensation interstitiel Fi. Cette btude rbvele la presence de plusieurs types de clusters pour des concentrations bgales ou supbrieures B 0,4 molyo. On observe pour la premiere fois avec le Dy3+ la raie A 125 cm-l que nous avons prbcbdemment attribube dans le cas de Nd3+ e t Ho3+ au mode longitudinal de la vibration de Fi dans un site trigonal. Un modhle laissait alors prbvoir la frbquence du mode transversal B 135 cm-l ; nous I'observons ici expbrimentalement pour la premiere fois. La raie A 42 cm-l prbcbdemment attribube B une transition blectronique de Dy3+ en site trigonal disparait quand la concentration augmente.
