Notes:
Energy barrier height and coercivity variation of a pair of interacting particles has been studied as a function of the bonding angle β for 0°≤β≤π/2 and applied field using the fixed step Monte Carlo simulation approach supplemented by the perturbation method. Coercivity Hc(β) of the system has local maxima at β=0 and π/2, and a global minimum at β(similar, equals)65°, and remains depressed compared to the noninteracting case for β≤30° at any temperature. The barrier height behaves similarly. Due to the random nature of distribution dipole interaction, on average, leads naturally to a reduction in coercivity and energy barrier height in comparison with the noninteracting case. © 1999 American Institute of Physics.
