An analogue, for ferrimagnetism, of the Curie–Weiss model ferromagnet is introduced. The resulting structure, the Curie–Weiss–Neel model, is based on a two sublattice description in which spins of ...read more

A compensation temperature induced by a crystal field interaction in a ferrimagnetic mixed Ising system
TL;DR: In this article, a mixed two-sublattice ferrimagnetic Ising system with a crystal field interaction was investigated by the use of the effective field theory with correlations.

Renormalization group treatment of the mixed-spin system in d-dimensional lattices☆
TL;DR: In this article, the critical properties of the d-dimensional mixed-spin model were studied by using the mean-field renormalization group and the phase diagram and estimates of the critical exponent were obtained.

The behaviour of a ferrimagnet near the neel point
Roger G. Bowers,B.Y. Yousif +1 more
TL;DR: In this paper, the high-temperature ferrimagnetic critical behavior of the initial susceptibility of a mixed-spin Ising model is studied using series expansions, which tends to support the conjecture that the critical exponents Γ N and Γ C near the Neel and Curie points are equal in value.

Spin-wave theory of layered Heisenberg ferrimagnets
TL;DR: In this paper, the effect of interlayer coupling on the magnetic properties of layered ferrimagnets using spin-wave theory was studied using spin wave theory and the sublattice magnetization was calculated for different inter-layer coupling strengths and temperatures.

Non-Convex Multipartite Ferromagnets
TL;DR: In this paper, a multipartite ferromagnetic model without self-interactions between spins of the same party was investigated, and the free energy and phase transition for all zero external fields were studied.
