Magneto-optical properties of neodymium-doped LiYF4

Abstract: In this paper we demonstrate the validity of a semi-empirical approach to describe the magneto-optical properties of lanthanide 31 complexes. The polarised absorption (IR-VIS-UV), magnetic circular dichroism (MCD) and magnetic susceptibilities of a LiYF :Nd 4 (1.5%) single crystal were recorded and analysed in a temperature region of 4.2 K up to room temperature. The crystal structure is obtained by means of X-ray analysis. Starting values of the free ion, crystal field and intensity parameter sets were obtain… Show more

“…In the scheelite-structured crystal LiYF 4 , the impurity Nd 3+ replaces the host Y 3+ and forms a 0932-0784 / 04 / 0400-0235 $ 06.00 c 2004 Verlag der Zeitschrift für Naturforschung, Tübingen · http://znaturforsch.com tetragonally distorted [NdF 8 ] 5− cluster [5,6]. For an Nd 3+ (4f 3 ) ion under tetragonal symmetry, its ground 4 I 9/2 configuration may be split into five Kramers doublets because of the spin-orbit coupling and tetragonal crystal-field interactions.…”

“…In LiYF 4 , the Y 3+ ion is coordinated to eight nearest F − ions which form the edges of a slightly distorted dodecahedron with S 4 local symmetry [5]. Because of the rather small distortion from D 2d to S 4 [11 -14], the imaginary parts of the rank-4 and rank-6 crystal-field parameters are very small, as pointed out in [13,15], and so their contributions to the coefficient C( 4 I 9/2 ;Γ γ (γ ) M J1 ) or C( 4 I 9/2 ;Γ γ (γ ) M J1 ) in the basis Γ γ (γ ) , and hence to the EPR parameters may be regarded as insignificant.…”
