METHOD FOR FUNCTIONALIZATION OF MONO-ION MAGNETS, A COMPOSITE MATERIAL AND A MAGNETIC PLATFORM BASED ON IT FOR THE DEVELOPMENT OF PLATFORMS FOR QUANTUM COMPUTING, ULTRA-HIGH DENSITY DATA STORAGE AND SPIN QUBITS Russian patent published in 2023 - IPC H01F1/53 C01F17/30 

FIELD: molecular spinotronics.

SUBSTANCE: invention relates to the production of single molecular (SMM) and single ion (SIM) magnets. It can be used as information storage elements and platforms for quantum computing. Composite material for magnetic platforms for quantum computing and data storage of ultrahigh density and spin qubits comprises 15 vol.% of the [Er(HL)(L)]₄CHCl₃H₂O complex, where L is 2,6-bis(phenylhydrazone)pyridine, and 85 vol.% particles of Pr₁₆Dy₁₇Fe₄₂Co₂₄. The mentioned material was obtained by mixing the dusty complex [Er(HL)(L)]₄CHCl₃H₂O and Pr₁₆Dy₁₇Fe₄₂Co₂₄ microparticles in an agate mortar with a diamagnetic spatula for 10 min until a composite material was obtained in the form of a homogeneous mixture. The magnetic platform made of a composite material is made in the form of a tablet with a diameter of 51 mm and a height of 800 mcm, obtained by pressing on a manual hydraulic press at a pressure of 0.3 MPa and subsequent magnetization in an external magnetic field from 0 to 7 kOe.

EFFECT: reduced power consumption, possibility of selecting a ferromagnetic matrix for single-ion magnets and using SIM as local memory elements.
