Description:
Author(s): Zhe Wang, M. Schmidt, A. Günther, F. Mayr, Yuan Wan, S.-H. Lee, H. Ueda, Y. Ueda, A. Loidl, and J. Deisenhofer We report on the phonon spectrum of the spin-gapped quantum magnet Ba 3 Cr 2 O 8 determined by infrared spectroscopy, and on specific heat measurements across the Jahn-Teller transition in magnetic fields up to 9 T. Phonon modes split below the Jahn-Teller transition, which occurs at T JT =70 K as detected... [Phys. Rev. B 85, 224304] Published Thu Jun 28, 2012
