Abstract: The theoretical analysis of the physical foundations of a ferromagnetic gyroscope with nanoscale sensing elements is carried out. The starting point for such an analysis is the Einstein-de Haas effect, which consists in the fact that a ferromagnet, when magnetized along a certain axis, acquires a momentum (rotational momentum) relative to it, proportional to the acquired magnetized momentum. It is shown that in order to obtain a practically significant effect for gyroscopy, it is necessary to use pseudocrystals constructed from nanospheres, inside of which there are nanoscale ferromagnetic formations in a state of quantum levitation and having an extremely high specific magnetization. The magnetized pseudocrystal will have the total momentum of the nanoscale ferromagnetic formations, which retains its direction when the orientation of the pseudocrystal in the sphere changes. Such a pseudocrystal can be considered as a promising model of a ferromagnetic gyroscope.
