PPT-Classification of Magnetic materials

The origin of magnetism lies in the orbital and spin motions of electrons and how the electrons interact with one another The best way to introduce the different types of magnetism . In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir Sedative hypnotics depress or slow down the bodys functions These drugs are commonly referred to as tranquilizers sleeping pills or sedatives They were originally developed to treat medical conditions such as epileptic seizures as well as to treat a Helena Khazdozian.

The purpose of this research is to observe and study the effects of temperature variations on the formation of and magnetic properties of Iron/Platinum (FePt) nanoparticles. We hope to find properties that will suggest that FePt particles can be used for magnetic recording in computer storage devices or as a replacement to currently used rare earth metals..
