Magnetic dichroism on double excitonic transitions in antiferro and ferrimagnetic nickel compounds

摘要: Abstract We report, for the first time, experimental and theoretical results on magnetic circular dichroism (MCD) double excitonic transitions in materials. In case of an antiferromagnetic ordering mo MCD was detected corresponding ultra-violet absorption bands KNiF 3 , K 2 NiF 4 Rb . spin flop configuration appears as RbNiF ferrimagnet. The treatment agrees with experiments shows that phase is related to anisotropy exchange interactions. Its variation fiel depends upon tilt angle spins. Stress linear (SLD) are also reported must be ralated integrals.
