The quantitative analysis of magnetic and magneto-optical properties in praseodymium trifluoride

This paper first considers the effects of L-S interaction and the crystal field on both the 4f ground state and the 5d excited state of Pr3+ ions in the paramagnetic material PrF3, and further takes account of the splitting of the crystal-held ground levels caused by the effective superexchange field Hv and the applied field He, and then, using the model of double transition with the splitting of the ground state, calculates quantitatively the magnetic susceptibility X, specific Faraday rotation theta F, Verdet constant V, and their temperature dependence in PrF3. The theoretical calculations show that the magneto-optical effect and its temperature dependence in PrF3 are closely related to the superexchange interaction between Pr3+ ions. V-1 and X-1 are linearly dependent of T in the temperature range of 110K
