Possibility of superradiance by magnetic nanoclusters    [PDF]

V. I. Yukalov, E. P. Yukalova
The possibility of realizing spin superradiance by an assembly of magnetic
nanoclusters is analyzed. The known obstacles for realizing such a coherent
radiation by magnetic nanoclusters are their large magnetic anisotropy, strong
dephasing dipole interactions, and an essential nonuniformity of their sizes.
In order to give a persuasive conclusion, a microscopic theory is developed,
providing an accurate description of nanocluster spin dynamics. It is shown
that, despite the obstacles, it is feasible to organize such a setup that
magnetic nanoclusters would produce strong superradiant emission.
