Antiferromagnet on Pyrochlore Lattice in Spherical Approximation
R. Bundaru
Received February 12, 2023

   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.

Key words: Phase transition, antiferromagnetism, spherical model.
