•A ferrimagnetic nanoscale multilayer film has a simple cubic lattice.•The formula of the magnetization and the internal energy is given.•Surface effects on magnetic and thermodynamic properties have been studied.
Magnetic and thermodynamic properties of a nanoscale multilayer ferrimagnetic films have been studied within the effective-field theory with correlations. The general formula for magnetization and internal energy is given. Some interesting results have been shown in the phase diagrams, for example two compensation points exist in the range of surface physical parameters. The competition among the surface exchange coupling, the surface single-ion anisotropy and the surface transverse field have great influences on the magnetization, the internal energy and the specific heat in the nanoscale multilayer ferrimagnetic films.
Graphical abstractPhase transition curves of nanoscale multilayer ferrimagnetic films may show compensation behavior, which mainly comes from different characteristic thermal variations of the sublattice magnetizations.Figure optionsDownload full-size imageDownload as PowerPoint slide
