Quantum Materials for Advanced Spintronic and Sensing Applications

This book highlights quantum materials and their applications in spintronic and sensing technologies. It delves into key material classes, including topological insulators, Weyl and Dirac materials, two-dimensional van der Waals magnets, and non-collinear antiferromagnets among others. These systems are explored through the lens of their unique quantum properties, such as robust spin-momentum locking, spin-orbit coupling, topologically protected surface states, high magnetoresistance, and manipulation of quantum metrics. By integrating quantum phenomena such as spin waves, nontrivial superconductivity, nonlinear transport, tunneling effects, and symmetry-driven topological states, spintronic devices based on these materials promise transformative advantages: ultrafast switching, wideband operation, higher data densities, and energy-efficient operation.
