Boson Peak in Vanadyl Pyrophosphate — •Sascha Eschborn, Swantje Kuhn, and Rudolf Feile — Technische Universität Darmstadt
We present the boson peak in amorphous vanadyl pyrophosphate ((VO)2P2O7) measured by Raman spectroscopy. Polarized and depolarized spectra taken at different temperature lead to the conclusion that boson peak and quasielastic scattering also observed are of a different microscopic origin.
