The quantum-spin $S=1/2$ chain system ${\mathrm{Cs}}_{2}\mathrm{Cu}{\mathrm{Cl}}_{4}$ is of high interest due to competing antiferromagnetic intrachain $J$ and interchain exchange ${J}^{\ensuremath{'}}$ interactions and represents a paramount example

Materials based on a crown ether complex together with magnetic ions, especially Cu(II), can be used to synthesize new low dimesional quantum spin systems. We have prepared the new crown ether complex Di-\mu-chloro-bis(12-crown-4)-aquqdichloro-copper

Crystallography deals basically with the question Where are the atoms in solids? The purpose of this chapter is to briefly introduce the basics of modern crystallography. The focus is on the description of periodic solids, which represent the major p

Depending on the crystal growth conditions, an orthorhombic (O-type) or a tetragonal (T-type) structure can be found in the solid solution ${\rm Cs}_{2}{\rm CuCl}_{4-x}{\rm Br}_{x}~(0\leq x\leq 4)$ . Here, we present measurements of the temperature-d

Materials close to a quantum-critical point – a zero-temperature phase transition – exhibit anomalous thermodynamic properties also at finite temperatures. Close to a magnetic field-induced quantum-critical point, for example, the finite-temperat

We present a structural analysis of the substituted system (Ba$_{1-x}$Sr$_{x}$)CuSi$_{2}$O$_{6}$, which reveals a stable tetragonal crystal structure down to 1.5 K. We explore the structural details with lowtemperature neutron and synchrotron powder

Magneto-acoustic investigations of the frustrated triangular-lattice antiferromagnet Cs2CuCl4 were performed for the longitudinal modes c11 and c33 in magnetic fields along the a-axis. The temperature dependence of the sound velocity at zero field sh
