Ferromagnetic chiral hybrid organic-inorganic perovskites — •Muskan Nabi and Alessandro Stroppa — CNR - Institute for SuPerconductors, INnovative materials, and devices Italy

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 newly synthesized ferromagnetic chiral hybrid inorganic perovskite and their 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 will be discussed.
