Revised Measurements and Interpretation of Magnetic Properties of Oriented CeF3 Single Crystals

Abstract

© 2016 Springer Science+Business Media New YorkWe report the magnetic susceptibility and magnetization of the single-crystal CeF(Formula presented.) precisely measured in external magnetic field-directed B(Formula presented.)c and B(Formula presented.)c in wide ranges of temperatures from 1.8 to 300 K and magnetic field strength of 0–40 kG. Magnetic susceptibility, magnetization, and Ce(Formula presented.) Stark energies of CeF(Formula presented.) have been calculated in the framework of the crystal field theory; good agreement with the experimental data has been achieved in the whole range of temperatures and magnetic fields without taking into account the mixed-valent Ce(Formula presented.)-Ce(Formula presented.) behavior or super-exchange interaction of cerium ions that have been proposed before. Anomalous behavior of the magnetic susceptibility near T (Formula presented.) 50 K is naturally explained in the crystal field model.
