Competition Between the Inter- and Intra-sublattice Interactions in Yb 2 V 2 O 7

February 27, 2015
Author(s)
Z. L. Dun, J. Ma, H. B. Cao, Yiming Qiu, John R. Copley, T. Hong, M. Matsuda, J. G. Cheng, M. Lee, E. S. Choi, S. Johnston, H. D. Zhou
We studied single crystals of Yb 2V 2O 7 using dc and ac susceptibility measurements, elastic and inelastic neutron scattering measurements, and linear spin wave theory. The experimental data shows a ferromagnetic ordering of V 4+ ions at 70 K, a short
