The article discusses the principles of information processing by nanomagnetic logic devices consisting in manipulating the magnetization of individual magnetic nanoparticles in a single-domain state and combined into a logical network. In a single-domain state, nanoparticles have uniaxial magnetic anisotropy, which makes them a bistable system suitable for binary coding of information: the magnetization down corresponds to a logical "0", the magnetization upwards is "1". These two states are separated by an energy barrier, the height equal to the energy of the magnetic anisotropy. The considered logical network, consisting of magnetic nanoparticles, implies an absolutely new way of carrying out logical operations. We are talking about a network of nanomagnets connected by a dipole interaction and admitting the existence of intermediate frustrated states, analogous to quantum entanglement.
Keywords:information processing, nanomagnetic logic device¸ spintronics.
