Terahertz (THz) time domain spectroscopy (THz-TDS) of a CoCr 2 O 4 and ZnCr 2 Se 4 single crystals have been performed under magnetic fields up to 10 Tesla and low temperatures. We observed the magnetic resonances originated from the spin dynamics of inter-sublattice exchange and screw spin structur...
