High field ESR measurements of a single crystal of the spin frustrated spinel compound MgCr 2O 4 have been performed in the temperature range from 1.7 to 80K in the frequency range from 60 to 370 GHz. We found that MgCr 2O 4 is an easy-plane type antiferromagnet with the hard axis almost along the (100) direction below the Néel temperature T N. In order to obtain more detailed information, we have performed high field ESR measurements in an attempt to align the domains by applying a weak biaxial or uniaxial pressure. These results indicate that the structural phase transition is accompanied by a contraction along one of the (100) directions and the contracted (100) direction becomes the magnetic hard axis below T N.
