Anisotropic field dependence of the magnetic transition in Cu2Te2O5Br2

A. V. Sologubenko, R. Dell'Amore, H. R. Ott +1

We present the results of measurements of the thermal conductivity of Cu2Te2O5Br2, a compound where tetrahedra of Cu^{2+} ions carrying S=1/2 spins form chains along the c-axis of…
