The Origin of Magnetism and Negative Temperature Characteristic in Finite Level Magnetic System The magnetism of matter is a deceptively simple problem that is actually quite subtle. In history, magnetism was discovered by humans very early. But it is strange that such "simple" magnetism cannot be described by classical physics, which seems so powerful! Specifically, [...]
Magnetic anisotropy of FePt nanoparticles ABSTRACT. Magnetic anisotropy of FePt nanoparticles - We carry out a systematic theoretical investigation of Magneto Crystalline Anisotropy (MCA) of L10 FePt clusters with alternating Fe and Pt planes along the (001) direction. The clusters studied contain 30 - 484 atoms. We calculate the structural relaxation and magnetic moment of [...]
The physical and chemical properties of magnetic nanoparticles largely depend on the synthesis method and chemical structure. In most cases, the particles range from 1 to 100 nm in size and may display superparamagnetism. Types of magnetic nanoparticles Oxides: ferrites Ferrite nanoparticles or iron oxide nanoparticles (iron oxides in crystal structure of maghemite or magnetite) [...]
