Abstract:
Powder x-ray diffraction (PXRD) and single-crystal neutron scattering were used to study in detail the structural properties of the Cs2Cu(Cl4-xBrx) series, good realizations of layered triangular antiferromagnets. Detailed temperature-dependent PXRD reveal a pronounced anisotropy of the thermal expansion for the three different crystal directions of the orthorhombic structure without any structural phase transition down to 20 K. Remarkably, the anisotropy of the thermal expansion varies for diff...     »
