Author(s): Ch. Kant, M. Schmidt, Zhe Wang, F. Mayr, V. Tsurkan, J. Deisenhofer, and A. Loidl We report a linear dependence of the phonon splitting Δ ω on the nondominant exchange coupling constant J nd in the antiferromagnetic transition-metal monoxides MnO, FeO, CoO, NiO, and in the frustrated antiferromagnetic oxide spinels CdCr 2 O 4 , MgCr 2 O 4 , and ZnCr 2 O 4 . It directly confirms the theoretical... [Phys. Rev. Lett. 108, 177203] Published Thu Apr 26, 2012
