Dr. Hashim Mohammed Jabbar and Msc. Mohammed Hassan Abbas published a paper entitled Structural and Magnetic Characteristics of Polyol Synthesized Cobalt Nanoparticles with Ruthenium and Samarium Additives: A First-Order Reversal Curve Analysis in the IRAQI JOURNAL OF APPLIED PHYSICS, which is indexed in Scopus database. the study aims to Ru and Sm rare-earth element additives are added to Co NPs synthesized using a polyol method. Carbon is also used in the synthesis process to act as a surfactant. Structural, morphological and compositional characteristics of the resulting NPs are investigated via different techniques. Particular attention is paid to investigate magnetic behavior of Co NPs containing the rare-earth elements based on magnetic parameters obtained from hysteresis loop and FORC measurements.
