Crystal field and magnetism of Pr${}^{3+}$ and Nd${}^{3+}$ ions in orthorhombic perovskites

P. Novak, K. Knizek, M. Marysko +2

Fifteen parameters characterizing the crystal field of rare-earth ions in the RMO${}_3$ perovskites (R = Pr, Nd, M = Ga, Co) are calculated by expanding the local Hamiltonian express…
