    Sammanfattning : Magnetism is a familiar phenomenon, and is applied in a variety of devices, from simple ones, like compasses, to the more sophisticated magnetic hard disk drives. It is also known that the magnetization of a material can change, for example by heating or by exposure to an external magnetic field. LÄS MER

  2. 2. Elektronstrukturbaserad magnetiseringsdynamik

    Kandidat-uppsats, Institutionen för teknikvetenskaper

    Författare :Niklas Fejes; [2013]

    Sammanfattning : In this project a method used for performing accurate simulations on magnetization dynamics based on constrained field density functional theory has been validated and used for performing computations on a few magnetic materials. The method has been shown to simulate systems consisting of iron well, but there are still problems with simulations of alloys containing both magnetic and non-magnetic materials. LÄS MER
