New Perspectives for Cuprate Research: CLBLCO Single Crystals
Gil Drachuck, Meni Shay, Galina Bazalitsky +7
We report the successful growth of a large (CaLa)(BaLa)CuO (CLBLCO) single crystal. In this material, controls the maximum of Tc…
Softened magnetic excitations in the s = 3/2 distorted triangular antiferromagnet alpha-CaCr2O4
Dirk Wulferding, Kwang-Yong Choi, Peter Lemmens +5
The spin dynamics and magnetic excitations of the slightly distorted triangular s = 3/2 system alpha-CaCr2O4 are investigated by means of Raman spectroscopy and electron spin reson…
Dynamical lattice instability versus spin liquid state in a frustrated spin chain system
V. Gnezdilov, P. Lemmens, Yu. G. Pashkevich +4
The low-dimensional s=1/2 compound (NO)[Cu(NO3)3] has recently been suggested to follow the Nersesyan-Tsvelik model of coupled spin chains. Such a system shows unbound spinon excit…
Crossover from coherent to incoherent scattering in spin-orbit dominated Sr2IrO4
Mehmet Fatih Cetin, Peter Lemmens, Vladimir Gnezdilov +5
Strong spin-orbit interaction in the two dimensional compound Sr2IrO4 leads to the formation of Jeff=1/2 isospins with unprecedented dynamics. In Raman scattering a continuum attri…
