摘要

“我们开发了经典自旋系统(三维矢量)解的系统逼近的1/n展开方法，该方法可以描述具有复杂磁化模式的一般自旋-自旋相互作用和相。应用该方法对焦绿石晶体(如Gd2Ti2O7)的相变进行了研究，所得结果与实验结果定性一致。

Antiferromagnet on Pyrochlore Lattice in Spherical Approximation

"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
