Oral: Ferromagnetic chiral hybrid organic-inorganic perovskites

In recent years, chiral hybrid organic-inorganic perovskites where the organic cations are the “source” of chirality, have received great attention from the physics and chemistry community. Their functional properties enable the control of light, charge, and electron spins in the same materials. Here, we discuss the intriguing “chirality transfer mechanism” in a newly synthesized ferromagnetic chiral hybrid inorganic perovskite such as (R/S-3FP)₂CuBr₄ and its interplay with magnetism. Although the organic cations are chiral and polar molecules, their arrangement in the crystal structure results in a chiral non-polar space-group P2₁2₁2₁. Moreover, we discuss a new chirality order parameter such as the electronic chirality measure (ECM) aiming at quantify the molecular cation chirality taking into account ionic and electronic degrees of freedoms simultaneously. Also, the relation of ECM to physical properties of chiral hybrid perovskites can be discussed
