Tuning the spin dynamics of kagome systems
D. Wulferding, P. Lemmens, H. Yoshida +2
Despite the conceptional importance of realizing spin liquids in solid states only few compounds are known. On the other side the effect of lattice distortions and anisotropies on…
Magnetic properties of the antiferromagnetic spin-1/2 chain system -TeVO
Yu. Savina, O. Bludov, V. Pashchenko +3
The magnetic susceptibility and magnetization of high quality single crystal beta-TeVO4 are reported. We show that this compound, made of weakly coupled infinite chains of VO5 pyra…
Anomalous low-energy phonons in nearly tetragonal BiFeO3 thin films
K. -Y. Choi, S. H. Do, P. Lemmens +5
We present evidence for a concomitant structural and ferroelectric transformation around K in multiferroic BiFeO/LaAlO thin films close to the tetragonal phas…
Helical fluctuations in the Raman response of the topological insulator Bi2Se3
V. Gnezdilov, Yu. G. Pashkevich, H. Berger +3
The topological insulator Bi2Se3 shows a Raman scattering response related to topologically protected surface states amplified by a resonant interband transition. Most significantl…
Magneto-structural transitions in a frustrated magnet at high fields
V. Tsurkan, S. Zherlitsyn, V. Felea +7
Ultrasound and magnetization studies of bond-frustrated ZnCr2S4 spinel are performed in static magnetic fields up to 18 T and in pulsed fields up to 62 T. At temperatures below the…
Coupled spin-lattice fluctuations in a compound with orbital degrees of freedom: the Cr based dimer system Sr3Cr2O8
Dirk Wulferding, Peter Lemmens, Kwang-Yong Choi +5
We report on an extended fluctuation regime in the spin dimer system Sr3Cr2O8 based on anomalies in Raman active phonons and magnetic scattering. The compound has two characteristi…
