In this paper, we report the results of magnetic resonance spectroscopy ${\mathrm{EuFe}}_{2}{\mathrm{As}}_{2}$ single crystals. We observe responses, which are attributed to antiferromagnetic resonances Eu sublattice with orthorhombic crystal structure and different orientations twin domains relative external field. confirm validity recently proposed spin Hamiltonian anisotropic Eu-Eu exchange interaction biquadratic Eu-Fe interaction.
