Structural and magnetic properties of the quantum magnet BaCuTe2O6

We investigate the structural and magnetic properties of the new quantum magnet BaCuTe_2_6 This compound is synthesized for the first time in powder and single crystal form. Synchrotron X-ray and neutron diffraction reveal a cubic crystal structure (P4_12) where the magnetic Cu^{2+}ions form a complex network. Physical properties measurements suggest the presence of antiferromagnetic interactions with a Curie-Weiss temperature of...
