摘要
Magnetic molecular materials with a chiral configuration are attractive candidates for sensing, information storage, and spintronics. Herein, we report the first example of two-dimensional hybrid perovskite chiral ferromagnets, (R-MPEA)2CuCl4 and (S-MPEA)2CuCl4. These two compounds exhibit strong oppositely signed circular dichroism signals and clear ferromagnetic behaviors. Magnetic measurements revealed high saturation magnetization up to 12.5 emu g–1. The coexistence of strong chirality and ferromagnetism enabled successful study on their magneto-chiral dichroism spectra. These findings demonstrate a new materials platform for future magneto-optical and spintronic applications, providing insights to the structure–property correlation of chiral ferromagnetic perovskite.
