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…

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…

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…
