A numerical examination is conducted of microinstabilities in a plasma with a reversed magnetic field, maintained by electron and ion diamagnetic currents. Two types of instabilities are observed in a plane perpendicular to the magnetic field. One occurs in local regions with steep density gradient, while the other occurs at the center of the neutral sheet. The instability which occurs in a region with a density gradient can be identified as a lower hybrid drift instability. The Lower Hybrid Drift (LHD) instability is essentially electrostatic, and its frequency is nearly the lower hybrid frequency. A rapid cross-sheet current decrease takes place during the evolution of the LHD instability. The electron diamagnetic flow is largely disturbed by microscale electric fields produced by the instability, and is deformed into E x B vortices.
