Researchers at the Institute of Science Tokyo have made a groundbreaking discovery by demonstrating Raman optical activity (ROA) in an achiral, nonmagnetic crystal, specifically nickel titanium oxide (NiTiO3). Traditionally, ROA was believed to only occur in chiral molecules or materials exhibiting magnetic order. However, this study reveals that ROA can arise from a structural property known as ferroaxial order, which involves coordinated atomic rotations within the crystal lattice. The research team, led by Professor Takuya Satoh, used circularly polarized Raman spectroscopy to detect differences in the intensity of scattered light between left- and right-circularly polarized light, a hallmark of ROA. This effect was found to depend on the orientation of the crystal, indicating that the internal rotational order, rather than chirality, drives the observed optical activity. The findings, published in Physical Review Letters, challenge conventional views and suggest that optically inactive materials can exhibit chirality-like optical responses, paving the way for new optical measurement techniques and material discoveries.
