  Rare earth Fe B permanent magnets are usually used because of their excellent
magnetic performance at room temperature. The high price of these elements
pushes some researchers to find new alternatives. From rare earth elements
cerium (Ce) is considered as the most abundant and cheap, therefore, the
interest was focused to study the properties of alloys based on this element in
recent years. In this work, we investigate the magnetization behavior of CeFeB
nanodisks in presence of Dzyaloshinskii Moriya interaction. We show that
topological structures, Neel skyrmions, in particular, could be nucleated
spontaneously in this kind of system. We also study skyrmions behavior in the
presence of finite temperature. We demonstrate that CeFeB nanodisks could host
magnetic skyrmions at room temperature.
