Floating Zone Growth of Sr Substituted Han Purple: Ba$_{0.9}$Sr$_{0.1}$CuSi$_{2}$O$_{6}$

Abstract

We present a route to grow single crystals of Ba$_{0.9}$Sr$_{0.1}$CuSi$_{2}$O$_{6}$ suitable for inelastic neutron studies via the floating zone technique. Neutron single crystal diffraction was utilized to check their bulk quality and orientation. Finally, the high quality of the grown crystals was proven by X-ray diffraction and magnetic susceptibility.
