1 Magnetic free energy at elevated temperatures and hysteresis of magnetic particles
We derive a free energy for weakly anisotropic ferromagnets which is valid in the whole range of temperature and interpolates between the micromagnetic energy at zero temperature and the Landau free energy near the Curie point Tc. This free energy takes into account the change of the magnetization length due to thermal effects, in particular, in the inhomogeneous states. As an illustration, we ...

متن کاملRelativistic Thomas-fermi Model at Finite Temperatures
We briefly review the Thomas-Fermi statistical model of atoms in the classical non-relativistic formulation and in the generalised finite-nucleus relativistic formulation. We then discuss the classical generalisation of the model to finite temperatures in the non-relativistic approximation and present a new relativistic model at finite temperatures, investigating how to recover the existing the...
متن کاملSpinons in Magnetic Chains of Arbitrary Spins at Finite Temperatures
The thermodynamics of solvable isotropic chains with arbitrary spins is addressed by the recently developed quantum transfer matrix (QTM) approach. The set of nonlinear equations which exactly characterize the free energy is derived by respecting the physical excitations at T = 0, spinons and RSOS kinks. We argue the implication of the present formulation to spinon character formula of level k ...
متن کاملScaling in a toy model of gluodynamics at finite temperatures
In the limit of ξ ≃ aσ/aτ → ∞ the gluodynamics without the magnetic part of action ( SM ∼ 1/ξ) is considered as a self-contained model. The model is studied analytically in the continuum limit on an extremely large lattice ( Nτ → ∞ ). Scaling conditions for critical temperature and string tension are considered. The model shows trivial ( g ∼ aτ ) asymptotic freedom in the case of continuous gau...
