Dynamic regimes of the magnetic moment of a nanoparticle with an uniaxial or cubic anisotropy are studied. Regular oscillations with different attractor shapes and periods and regimes of chaotic and quasi-periodical dynamics are revealed. The dynamic bistability states are discovered; the transitions between the oscillation regimes belonging to bistability are obtained by means of the pulsed change in the alternating field amplitude. It has been shown that the 90°-remagnatization of the nanoparticle is caused by the alternating field action. The nanoparticle lattice parameters at which the dipole interaction effect on the oscillation regimes of magnetic momenta can be neglected are revealed.
