Abstract
The present work reconnoiters the dielectric, electrical, and magnetic properties of transition metal–doped lead sulfide nanoparticles (PbS-NPs) synthesized by co-precipitation technique. The particle size was assessed from the histogram obtained by transmission electron microscopy (TEM). Frequency- and temperature-dependent measurements of dielectric permittivity and ac conductivity have been carried out for transition metal–doped lead sulfide nanoparticles (PbS-NPs). The transition metal–doped lead sulfide nanoparticles show ferromagnetic nature with enhanced magnetization with the doping of Ni, Co, and Fe respectively as compared with pure lead sulfide nanoparticles. These nanoparticles may find its application in electronic storage and DMS spintronic devices due to their enhanced and regulated nature of dielectric and magnetic behavior.
