Magnetocaloric effect (MCE) and its potential most simple and evident application in magnetic cooling technology represent urgent issues that have been the subject of intensive global investigation over recent decades. The practical use of a material exhibiting a magneto-caloric effect in cooling technology necessitates a cyclic exposure of the material to a magnetic field. It is therefore imperative to undertake a comprehensive study of the magnetocaloric properties of materials subjected to alternating (or cyclic) magnetic fields. This paper presents an overview of the fundamental concepts pertaining to the effect, methodologies for the measurement of MCE in alternating magnetic fields, and the outcomes of MCE studies depending on the frequency of the magnetic field and the duration of exposure of materials to the alternating magnetic field.
