Investigation of antiferromagnetic magnon in VBr3
Magnetic van der Waals (vdW) crystals show promising potential for high-tech magnetic, magneto-electric, and magneto-optic applications. The discovery of 2D ferromagnetism in a monolayer CrI3 [1] at elevated temperatures has greatly promoted research in these materials. The large family of transition metal halides offers a large playground for systematic theoretical and experimental investigation of 2D magnetism. At present, we focus on the antiferromagnet VBr3, a member of the trihalide family in which intrinsic ferromagnetism in the single layer limit was discovered in CrI3, VI3, and even CrBr3. VBr3 magnetic structure also consists of ferromagnetic layers, which are, however, antiferromagnetically coupled through a weak vdW bond. Our very recent Raman spectroscopy experiment has elated antiferromagnetic magnon in VBr3 at the energy similar (smaller) to that of FM counterparts. The proposed experiment aims just to this magnetic excitation. That is, the dispersion of this magnetic excitation in reciprocal space is to be followed to prove its nature. The results will be subsequently discussed in the frame of other vdW materials.
