Talk Title: Elasto van der Waals Magnet
Series: Nano Science & Technology
Abstract: Van der Waals magnets have emerged as a powerful platform for exploring fundamental spin physics and potential applications in electrical and optical-driven spin-based devices. The ease of control of magnetic properties via external control knobs makes them particularly useful. In this talk, I will highlight our recent progress in tuning the magnetic properties of the newly discovered magnetic semiconductor CrSBr through uniaxial strain. This includes the coupling of exciton and interlayer magnetism, the reversible switching of antiferromagnetic to ferromagnetic phase transitions, and the strain-tuning of coherent spin waves (magnons) through optical spectroscopy of excitons. Lastly, I will discuss a strain-controlled van der Waals magnetic tunnel junction with programmable magnetic memory and probabilistic bit functionality, which holds potential for new memory and computing technologies.
