Abstract

We report the magnetic susceptibility and magnetization of the single-crystal CeF\(_{3}\) precisely measured in external magnetic field-directed B\(\vert \vert \)c and B\(\bot \)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\(^{3+}\) Stark energies of CeF\(_{3}\) 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\(^{3+}\)-Ce\(^{4+}\) behavior or super-exchange interaction of cerium ions that have been proposed before. Anomalous behavior of the magnetic susceptibility near T \(\sim \) 50 K is naturally explained in the crystal field model.
