High-Temperature Series Expansion for Spin-1/2 Heisenberg Models
Andreas Hehn, Natalija van Well, Matthias Troyer
We present a high-temperature series expansion code for spin-1/2 Heisenberg models on arbitrary lattices. As an example we demonstrate how to use the application for an anisotropic…
Magneto-acoustic study near the quantum critical point of the frustrated quantum antiferromagnet Cs2CuCl4
P. T. Cong, L. Postulka, B. Wolf +5
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-a…
Low-temperature structural investigations of the frustrated quantum antiferromagnets Cs2CuCl(4-x)Br(x)
Natalija van Well, Kateryna Foyevtsova, Saskia Gottlieb-Schoenmeyer +9
Powder X-ray diffraction (PXRD) and single-crystal neutron scattering were used to study in detail the structural properties of the Cs2CuCl(4-x)Br(x) series, good realizations of l…
Elastic constants and ultrasound attenuation in the spin-liquid phase of CsCuCl
S. Streib, P. Kopietz, P. T. Cong +5
The spin excitations in the spin-liquid phase of the anisotropic triangular lattice quantum antiferromagnet CsCuCl have been shown to propagate dominantly along the crystal…
Structural variations and magnetic properties of the quantum antiferromagnets Cs2CuCl4-xBrx
Pham Thanh Cong, Bernd Wolf, Natalija van Well +4
Depending on the crystal growth conditions, an orthorhombic (O-type) or a tetragonal (T-type) structure can be found in the solid solution Cs2CuCl4-xBrx (0 < x < 4). Here we presen…
Spin correlations and Dzyaloshinskii-Moriya interaction in CsCuCl
M. A. Fayzullin, R. M. Eremina, M. V. Eremin +7
We report on electron spin resonance (ESR) studies of the spin relaxation in CsCuCl. The main source of the ESR linewidth at temperatures K is attributed to th…
