INDUCTANCE COIL CORE (EMBODIMENTS) Russian patent published in 2019 - IPC H01F3/10 

FIELD: electricity.

SUBSTANCE: invention relates to production of magnetic bodies, in particular to structure of magnetic material with variable shape anisotropy for excitation of magnetic field in specified direction, and can be used for production of cores of inductance coil. Inductance coil core is made from a set of magnetic units with shape anisotropy, having long and short axes. Long axes of blocks are co-directional. Direction of magnetisation of the core is set along the long axis of the blocks. Magnetic blocks are separated by a layer of nonmagnetic material, the thickness of which is from 0.5 nm to 20 mcm. Size of blocks has ratio of long axis to short axis from 1.4 to 100. Core of inductance coil can be made of at least two layers, each of which consists of a set of magnetic units with shape anisotropy, having long and short axes. Each layer of blocks is separated from the next layer by a layer of non-magnetic material, having thickness of 0.4 nm to 2 mcm, and thickness of magnetic layers ranges from 0.4 nm to 2 mcm.

EFFECT: technical result is providing direction of magnetization of inductance coil core due to its implementation from pattern of magnetic elements units with shape anisotropy.
