Description

Two-dimensional (2D) materials with intrinsic ferromagnetism has attracted massive interest because of their potential applications in data storage and spintronics devices. Atomic layers of chromium triiodide (CrI3) are one of such 2D ferromagnetic (FM) materials that have been demonstrated to show long range FM order in its monolayer limit. The strong coupling between spin, lattice, and charge degrees of freedom in 2D CrI3 enables interesting magneto-optical effects in bulk and thin layers of CrI3. In this talk, I will present our recent magneto-Raman spectroscopy studies of magnons (spin waves), magnetism-induced phonons, and electron-phonon coupling in bulk and 2D CrI3.
