We live in a world where Quantum Physics underlies how atoms work. In ancient times, our knowledge was benighted and limited by the technology and measurement sciences. Nowadays, we have tremendous power to take a glimpse of the fascinating quantum world by a new paradigm that combines the work of material synthesis, advanced theory, high-performance computational calculation, and multi-length scales modern probes either in-house or at large-scale national facilities. We are in the golden age for the science of quantum materials and on the verge of future applications.

FexNbS2 PRX paper is in press!! https://journals.aps.org/prx/abstract/10.1103/PhysRevX.12.02100
The consequent insensitivity to external magnetic fields in antiferromagnets makes these materials promising for building spintronic devices, which store and transfer information in electron spins rather than just charge. One such material, the “van der Waals” antiferromagnet FexNbS2, has shown intriguing spintronic behavior: a rapid current-induced resistance switching that couples to the antiferromagnetism. But the magnetic properties underlying the resistance were unknown. Here, we report on highly tunable magnetic states via bulk characterizations and neutron scattering measurements in this material that are controlled by magnetic defects. Such defects typically inhibit magnetism because of the disorder, rather than creating new functionality.
Our work will stimulate more exploration on such unusual antiferromagnetic spintronic behavior and provide a new avenue for defect-induced controllability of the magnetic state in other van der Waals systems. That should, in turn, enable device scientists to design the very best materials for the spintronic devices of the future.
