Thermal and magnetic properties of chalcogenide CZFTS nanoparticles for solar cell application

An attempt is made to resolve the controversy related to the reconstruction mechanism of magneto-optical stannite/kieserite crystal structure with a random mixture of two quaternary compounds of Cu2ZnSnS4-Cu2FeSnS4 while the identification of phase formation by XRD is difficult. Since the Fe is surprisingly emerged on the Cu position while Fe is replaced by Zn. The induced dynamical sliding by Cu-ionic-host could be existed which is strongly consequence of magnetic exchange competition (F.M and AFM) through the thermos remanent magnetic reflected on DTA thermal loop. Towards the distortion of infra-plane "a-b", the volume unit cell and c/a are decreased to minimize Gibbs free energy where the band gap energy is also decreased. The broad maximum of Raman spectroscopy is almost decreased linearly. A strong competition between F.M and AF.M due to the distribution of exchange interaction are evident in x <= 0.5 which is dominated by AF.M on x=1.
