Abstract :
The resonance interaction of grains is theoretically demonstrated to be important in magnetic recording media with weak intergranular magnetostatic coupling. It causes energy transfer between grains and the collective motion of grains, which increases the reversal time and is a key to explain a thermal stability of magnetic memory
