Query: Optimal conditions for magnetization reversal of nanocluster assemblies
  with random properties   Magnetization dynamics in the system of magnetic nanoclusters with randomly
distributed properties are studied by means of computer simulations. The main
attention is paid to the possibility of coherent magnetization reversal from a
strongly nonequilibrium state with a mean cluster magnetization directed
opposite to an external magnetic field. Magnetic nanoclusters are known to be
characterized by large magnetic anisotropy and strong dipole interactions. It
is also impossible to produce a number of nanoclusters with identical
properties. As a result, any realistic system of nanoclusters is composed of
the clusters with randomly varying anisotropies, effective spins, and dipole
interactions. Despite this randomness, it is possible to find conditions when
the cluster spins move coherently and display fast magnetization reversal due
to the feedback action of resonator. By analyzing the influence of different
cluster parameters, we find their optimal values providing fast magnetization
reversal.
