Kézsmárki We studied spin excitations in the magnetically ordered phase of the noncentrosymmetric Ba 2 CoGe 2 O 7 in high magnetic fields up to 33 T. In the electron spin resonance and far infrared absorption spectra we found several spin excitations beyond the two conventional magnon modes expected for such a two... [Phys. Rev.
