Abstract:
It is shown that hysteresis can be observed in an assembly of chaotic distributed particles without intrinsic magnetic anisotropy due to interparticle magnetostatic interactions. To take this interaction into account, pair approximation and computer simulation of the remagnetization process are used. The investigation is restricted to the case of identical spherical particles with constant magnetic moment. Consideration is given to the case of zero temperature and large dissipation, which results in the quasistatic remagnetization process, so that the moment of the particle is always aligned in the field direction.<>
