(American Physical Society, 2018-04-16) Carriço, Arthur da Silva; Dantas, Ana Lucia; Oliveira, L. L.; Pedrosa, S. S.; Rebouças, G. O. G.; Silva, R. B.; Araújo, José Humberto de
We report a theoretical study of core-shell dipolar interaction effects on the energy product of hard/soft SmCo5@Fe core-shell spherical nanoparticles. We show that the impact of the core-shell dipolar interaction on the shell reversal process is tunable by the values of the core diameter and shell thickness. Maximum energy product optimization requires small core diameters, and the energy product enhancement may reach more than 370% for small core diameters SmCo5@Fe core-shell nanoparticles
