Raman scattering due to a one-magnon excitation process in $\mathrm{Mn}{\mathrm{V}}_2{\mathrm{O}}_4$

S. Miyahara, K. Takubo, T. Suzuki +2

Unconventional peak structure in the Raman spectra due to magnon excitation at low temperature is observed in spinel magnet $\mathrm{Mn}{\mathrm{V}}_2{\mathrm{O}}_4$, where a noncollinear spin state is rea…
