Abstract
"We develop an 1/n expansion method for the systematic approximation of the solutions of classical spin systems (tri-dimensional vectors) which can describe general spin-spin interactions and phases with complex magnetization pattern. This method is applied to study the phase transitions observed in pyrochlore crystals (e.g. Gd2Ti2O7) and the results have qualitative agreement with the experimental ones."
期刊介绍：
Romanian Journal of Physics was first published in 1992 as a continuation of the former Revue Roumaine de Physique (ISSN: 0035-4090), a journal publishing physics and engineering scientific papers established 1956 with deep roots in the early history of the modern Romanian physics.
Romanian Journal of Physics is a journal of the Romanian Academy published by Editura Academiei Romane (eA). The journal has an international character intended for the publication of original physics contributions from various sub-fields including the following:
-Theoretical Physics & Applied Mathematics
-Nuclear Physics
-Solid State Physics & Materials Science
-Statistical Physics & Quantum Mechanics
-Optics
-Spectroscopy
-Plasma & Laser Physics
-(High Energy) Elementary Particles Physics
-Atomic and Molecular Physics
-Astrophysics
-Atmosphere (Environmental) & Earth Science
-Environmental Protection
