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.
