Magnetoresistive properties of nanostructures containing 2D ferromagnetics
In recent years, spintronics and two-dimensional (2D) materials research fields have grown rapidly, driven by the demand for low-power, miniaturized, and highly functional electronic and quantum devices. Tunnelling magnetic junctions (TMJs), composed of ferromagnetic layers separated by a thin insulating barrier, are widely used in magnetic sensors, MRAM memory, and other spintronic devices. Their operation is based on quantum tunnelling and spin polarization of charge carriers; therefore, their electrical properties are highly sensitive to material choice and interface quality.
The discovery of ferromagnetic ordering in two-dimensional van der Waals materials has opened new developing routes for next-generation mixed-dimensional or fully 2D TMJs with electrically tuneable magnetic properties and reduced technological constraints. However, the advancement of this technology is currently limited by challenges related to scalable synthesis, layer transfer, and reproducibility.
The aim of this work is to investigate tunnelling magnetic nanostructures based on two-dimensional ferromagnetic materials and conventional ferromagnets, focusing on their electrical properties and potential applications in spintronic and quantum devices.
