Antiferromagnetic Spintronics

Spintronics is a research field that studies the active control and detection schemes of the spin degrees of freedom in solid-state systems. Over decades, novel phenomena have been discovered in the variety of ferromagnet-based systems, forming the core elements for spintronic applications. Recently, effort in the field has been deployed to enhance the device switching speed and reduce power consumption. In this regard, antiferromagnets are outstanding candidates to replace the widely used ferromagnets in the next generation of spintronic applications due to their robustness against magnetic perturbations, absence of stray fields, and ultrafast dynamics.

We are exploring the physical properties related to the antiferromagnetic (AFM) symmetry, analyzing their responses against the reorientation of the AFM order parameter (Néel vector), and designing new material platforms with promising functionalities for AFM spintronics.

Research highlights:

  1. AFM tunnel junctions
  2. An AFM Dirac nodal line metal
  3. Nonlinear anomalous Hall effect due to Berry curvature dipole in antiferromagnets
  4. The noncollinear AFM antiperovskite family: A new AFM spintronic platform
  5. Ferroelectric control of anomalous Hall effect in antiferromagnets
  6. Antiferromagnets as promissing spin sources in experiments
