Pengaruh Doping Chromium Terhadap Sifat Magnetik Nanopartikel Oksida Besi Dan…

ABSTRACT The purpose of this study is to determine the magnetic properties expressed in the hysteresis loop as well as the morphology of Iron sand Iron Oxide nanoparticles of Logas Village, natural sand, which are doped with Chromium. The separation between magnetic and non-magnetic particles is investigated using the strong magnet Neodymium Iron Boron (NdFeB). Magnetic nanoparticle preparatio…
