Spin-wave spectrum of CoFe2O4 measured on the MAPS spectrometer (left) and the corresponding spin-wave calculation (right).

The large ~60 meV splitting between the two magnon branches originates from the strong imbalance of molecular fields on the A and B cation sites, as illustrated in the inset crystal structure.
