Abstract

Tetragonal ferrimagnetic spinel Mn3O4 shows complex magnetic phase transitions due to competing antiferromagnetic interactions involving Mn2+/3+ ions with difference valences. Using magnetization and neutron diffraction measurements, we propose that its tetragonal lattice possesses an instability towards orthorhombic distortion in zero field well below TN. The direction of the observed instability suggests that the anomaly is related to lifting of the persistent geometrical frustration via spin-lattice coupling.
