Tailoring the structural and magnetic properties of sol-gel derived Sm-Co nanogranular films

► Sol-gel method is exploited for the processing of Sm-Co nanogranular films. ► Role of Sm:Co precursor ratio on the film characteristics is investigated. ► SmCo5, Sm2Co7 and Sm2Co17-phases crystallized for molar ratios of 1:5, 1:7 and 1:9. ► Hc values of 1.78, 2.94 and 2.12 kOe resulted for the three distinct magnetic phases.
