ISLAND MAGNETORESISTIVE SENSOR Russian patent published in 2024 - IPC H10N50/10 

FIELD: measuring.

SUBSTANCE: invention can be used to control the value of magnetic field induction in various devices. Essence of the invention consists in the fact that the island magnetoresistive sensor consists of ferromagnetic layers of alternating metals of magnetically soft Ni and magnetically hard Co, wherein the ferromagnetic layers are island films, the base used is a dielectric substrate made from glass, ceramics or glass-ceramic, and conducting copper contact pads are located above and below the array of layers. Between island ferromagnetic layers the sensor contains a dielectric layer of Al₂O₃.

EFFECT: possibility of detecting weak magnetic fields with induction of 0.02-200 mcT with accuracy of about 1 nT at pressure from 10⁵ Pa to 10^-3 Pa and temperature from minus 100 °C to plus 350 °C.
