spintronikan

Spintronikan is a field of physics and engineering focused on the manipulation of electron spin in solid-state systems to improve information processing and storage technologies. It extends traditional spintronics by emphasizing integration with standard semiconductor platforms, scalable fabrication, and hybrid architectures that combine magnetic, superconducting, and topological materials.

Key concepts include spin polarization, spin injection and detection, magnetoresistance effects such as giant magnetoresistance and tunneling magnetoresistance, and the role of spin-orbit coupling in creating spin currents via the spin Hall effect. Spin coherence and relaxation times determine how long spin information persists, influencing device design.

Materials and devices: Common materials studied are ferromagnetic metals (Fe, Co, Ni), magnetic alloys, and non-magnetic semiconductors, as well as two-dimensional materials, topological insulators, and Heusler compounds. Device structures include magnetic tunnel junctions, spin-field-effect transistors, spin-based qubits for quantum information, and hybrid memristive devices.

Applications and potential impacts include non-volatile memory with high endurance (MRAM), spin-based logic, high-sensitivity magnetic sensing, and opportunities in neuromorphic and quantum information processing. Spintronikan aims to reduce energy consumption and enable new computing paradigms through spin manipulation.

Challenges remain, including preserving spin coherence at room temperature, achieving scalable integration with mainstream CMOS fabrication, controlling interface properties, and reducing device-to-device variability. Research is international in scope, with open measurement standards and collaboration across materials science, physics, and electrical engineering.
