Abstract
The kinetic effects of magnetic drift resonance on the drift cyclotron loss cone instability (DCLC) are studied in detail both analytically and numerically. It is found that the effects of inhomogeneous magnetic field in high β plasmas are important, the kinetic resonance act as a dissipative effect, which can enhance the instability and broaden the unstable region of negative energy DCLC mode. Finite β effects do not play the stabilization role predicted by the theories under the fluid approximation.
