Absorption spectrum of the Mn2+ ions in crystals of lanthanum manganese double nitrate and praseodymium manganese double nitrate

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The optical absorption spectrum of the Mn2+ ions in the two double nitrates La2Mn3(NO3)12 ⋅ 24H2O and Pr2Mn3(NO3)12 ⋅ 24H2O were measured up to 30000 cm−1. Uniaxial stress was applied to the crystals to determine the multiplicity of the observed zero phonon lines belonging to the transitions from the groundstate6 A 1 (6 S) to the excited states4 E(4 G) and4 T 2(4 D). The Zeeman effect of the states4 A 1(4 G) and4 E(4 G) was measured with magnetic fields up to 6.4T. The effect of covalency and trigonal field, especially to the states4 A 1 (4 G) and4 E(4 G), is briefly discussed.
