Cerium, one of the rare earth elements, has a 4f1 electron and exhibits a wide variety of physical properties. Since 4f electrons are in the inner shell, direct interactions are very weak, and thus the hybridization of the 4f electrons and conduction electrons is dominant to give rise to various magnetic properties. This article describes the magnetic properties of CeTSi3 (T = transition metal) with broken inversion symmetry, van der Waals compounds CeTe3, and Ce5Si3 with a Shastry-Sutherland lattice, using neutron experiments as the main method of study.
