This study investigates the coexistence of ferroelectric, magnetic, and crystallographic chirality in hybrid organic-inorganic perovskites [(R/S)-β-methylphenethylamine]2CuCl4. Through experimental and theoretical methods, the researchers demonstrate that these materials exhibit intralayer ferroelectricity and A-type antiferromagnetic order, along with chirality-dependent magnetic circular dichroism (MCD) characters. The Landau symmetry mode analysis reveals a novel mechanism for chirality transfer, involving the coupling of non-chiral distortions characterized by a pseudo-scalar quantity, ξ = p·r, where p represents the ferroelectric displacement vector and r denotes the ferro-rotational vector. This mechanism links molecular chirality with the non-chiral ferroelectric and ferro-rotational moments of the inorganic framework, enabling the transfer of chirality from the organic molecules to the inorganic framework. The study highlights the correlation between crystallographic chirality and ferroic behaviors, paving the way for exploring novel chiroptical and magnetoelectric phenomena in hybrid systems.This study investigates the coexistence of ferroelectric, magnetic, and crystallographic chirality in hybrid organic-inorganic perovskites [(R/S)-β-methylphenethylamine]2CuCl4.
