Abstract
Nanoparticles often play a role in the form of groups. The collective properties of magnetic nanoparticles will be changed as a result of the inter aggregation mode and the morphology of the particles. In this thesis, magnetic properties and magnetocaloric effects of one dimensional chain nanoparticles in magnetic field are mainly studied, which lays the foundation for further clinical applications.Through the simulation research on the multi physical coupling, the changes of collective magnetic properties and magnetocaloric effects of one dimensional structure nanoparticles assembled by magnetic field are expounded theoretically. Concretely, Comsol Multiphysics software is applied, and magnetic flux density images of one dimensional chain magnetic nanoparticles caused by alternating magnetic field are obtained with different direction. Furthermore, alternating magnetic fields are induced, magnetic flux density and electromagnetic heat images of one dimensional chain magnetic nanoparticles are obtained with different diameters and spaces, and the magnetic field distribution and the magnetic heat distribution are analyzed. Through multiple one dimensional chain nanoparticles images of different magnetic heat found that one dimensional chain nanoparticles mutual effects between adjacent particles, result in the simulation results obviously.
