We study the reversal times of the macrospine in individual ferromagnetic and antiferromagnetic nanoparticles by using matrix continued fraction method. It’s shown that, at a high damping regime and at the small barrier, the behavior the relaxation of the magnetization in the ferromagnatic is similar to those for antiferromagnetic nanoparticle
