Dimensional crossover in a layered ferromagnet detected by spin correlation driven distortions
Abstract
Exploring lattice distortions from magnetic short-range ordering (SRO) facilitates the understanding of magnetic long-range ordering (LRO). Here the authors apply high-multipole nonlinear optical polarimetry to track SRO induced distortions in CrSiTe3, showing that LRO is established via a crossover from two- to three-dimensional SRO.
