Description
Magnetization of two dimensional O(3) Heisenberg ferromagnet is investigated using perturbation theory for type-B Nambu-Goldstone bosons, quantum Monte Carlo simulations an nonlinear spin wave theory.
By calculating loop corrections to the magnon self-energy, in combination with QMC data and spin wave theory, we discuss the applicability of effective field theory for two dimensional O(3) ferromagnet in external magnetic field.
