Isotropic absorption lines of electron paramagnetic resonance, which can be described as single Lorentzian shape, are observed. The g value of paramagnetic state is estimated to be 1.983 at 265K. Magnitude of D vector of Dzyaloshinskii-Moriya interaction is estimated to be 0.36K from Moriya's formula using the obtained g value. Powder patterns of antiferromagnetic resonance (AFMR) with large antiferromagnetic gaps are observed below T N=140K. Two antiferromagnetic gaps at zero field have been estimated to be 181GHz (6.5T) and 338GHz (12.1T), and a spin flop transition field have been estimated to be 3.5T from widely observed frequency-field diagram at 1.9K. Although obtained AFMR modes seem to be typical AFMR modes of two sublattice antiferromagnet with triaxial magnetic anisotropy, the obtained zero-field gap is twice as large as the obtained spin flop transition field which suggests the unconventional antiferromagnetic order.
