interaction between the Grand total angular momentum and external magnetic field. A very schematic picture of the energy levels of 87Rb under a weak external field is shown in Fig. 1. After applying an weak external magnetic field on the atom, the formally degenerated energy level with same F will further split into 2F+1 sublevels, denoted by mF which is the projection of Grand total angular momentum to the direction of external field B0. Fig. 1 Until now we haven't mention any thing about the optical

Abstract Conductive polymers or, intrinsically conducting polymers (ICPs) are organic polymers that can have metallic conductivity or semiconductivity via conjugation and co-doping. Polypyrrole (PPy) as a kind of heterocyclic conjugated conductive polymers is considered to be the most prospective electric conductive polymer due to its relatively high conductivity, stability, and other characteristics. Recently, PPy /magnetic nanoparticles composite materials have become a research hotspot, for its
