Abstract: During the past 10 years there has been a great demand in molecular science to expose different physical properties in one 2D single crystalline material, especially in metal(inorganic)−organic hybrid perovskite systems. Here, each moiety has showing its own significant characteristic properties. The co-existence of different properties (electrical, optical and magnetic) in one single material is more beneficial for the information storage devices and the solar energy conversion. Several scientific research communities have been inputting their efforts to generate different kind of materials with various compositions. In accordingly the research has been focused what is the synergy involved in it, when, how and why certain moieties are easily coupled. The most important that the chemist developed those materials and how the metal-organic systems are exclusive and has considerable consequence on the structural and physical properties of the inorganic moieties. So far, many materials have been scrutinized and some of the systems have displaying magnetic, electric, toroidic properties which are considered under Multiferroic. Here our group has been grown a ferro and antiferromagnetic 2D single crystal hybrid perovskite material ecofriendly solvents at ambient temperature condition. We have investigated the structural, magnetic, and dielectric properties of the organic–inorganic hybrid material with Cupper (II) bromide and Penylethylamine (C6H5CH2CH2NH3)2 as spacer and demonstrate that spontaneous antiferromagnetic and layered ferromagnetic order sets in below 300K having a transition temperature with 13K.
