Topological quantum materials for spintronics

Spintronics is an innovative field that exploits the intrinsic spin property of electrons instead of their charge, holding the promise of revolutionizing conventional electronic devices. Over the past decade, researchers have been actively exploring new materials as potential replacements for traditional spintronic materials. This endeavor is driven by the aspiration to create spintronic devices with ultralow power consumption, ultrahigh storage density, and remarkable stability. In recent years, topological quantum materials (TQMs) have attracted considerable interest due to their unique band structure and exceptional properties. These materials carry the potential to pave the way for breakthroughs in the design of spintronic devices, offering promising solutions to solve challenges currently faced in the field of spintronics. In this review, we first introduce the properties of various TQMs, including band structure and crucial transport properties. Subsequently, we focus on the diverse applications of TQMs in spintronics. Delving further, we discuss the current challenges and the potential directions for advancing and exploring TQMs.
