Author(s): V. Gnezdilov, P. Lemmens, Yu. G. Pashkevich, Ch. Payen, K. Y. Choi, J. Hemberger, A. Loidl, and V. Tsurkan We investigate the origin of large magnetocapacitive effects in CdCr 2 S 4 single crystals focusing on phonon anomalies in the fluctuation regime T 〈 T * = 130 K and with the onset of ferromagnetic order T c = 84.4 K. The observation of longitudinal optical and formerly infrared active modes for T <... [Phys. Rev. B 84, 045106] Published Wed Jul 06, 2011
