Abstract:
The functional integral method and Heisenberg model for localised spins were used for the
calculation of the thermodynamics characteristics of magnetic films. It was shown in the Gaussian
approximation that the Curie temperature is strongly reduced when the film's thickness reduces to the
nanometer region. ?? 2010 IOP Publishing Ltd.
