Abstract

Realization of the tetragonal phase of Cs₂CuCl₄ is possible using specific crystal growth conditions at a temperature below 281 K. This work deals with the comparison of the magnetic susceptibility and the magnetization of this new tetragonal compound with the magnetic behavior of tetragonal Cs₂CuCl_2.9Br_1.1, Cs₂CuCl_2.5Br_1.5, and Cs₂CuCl_2.2Br_1.8 and presents consistent results for such quasi 2-D antiferromagnets. Structural investigation at low temperature for Cs₂CuCl_2.2Br_1.8 shows no phase transition. The structure remains in the tetragonal symmetry I4/mmm. Furthermore, several magnetic reflections corresponding to the propagation vector k = (0, 0, 0) are observed for this tetragonal compound through neutron diffraction experiments below the magnetic phase transition at T_N = 11.3 K confirming its antiferromagnetic nature.
