Low-temperature magnetization in nanofilms

Sajfert, Vjekoslav; Popov, Dušan; Tošić, Bratislav - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 4, pp. 325-331

The low-temperature magnetization of a film was analyzed by the use of exact Bose representation of spin operators that does not suffer from the presence of unphysical states. The magnetization of thin films has exponentially small temperature correctness, so that Dyson’s proof about...
