On Tuesday, October 22nd, we will continue with the MAGNET Section seminars. The seminars are held every 2nd Tuesday, at 9:15.
At this seminar, we will hear a presentation by Master students Mikkel C. Larsen and Mikkel Ravn-Feld on: “Monte Carlo Simulations of magnetic properties in LiMPO4’’ (see abstract below).
The seminar will take place in Building 307, Room 064.
You can also join the seminar via Zoom (https://dtudk.zoom.us/j/61492165922)
Abstract
Monte Carlo Simulations of magnetic properties in LiMPO4
Monte Carlo Simulations (MCS) is a class of simulations that uses randomly generated numbers to obtain numerical results. In our bachelor project, we used a Metropolis Monte Carlo approach which - starting from anisotropy and exchange energies determined from spin wave studies – allows us to determine the magnetic ground states of Lithium Orthophosphates with the chemical formula LiMPO4 (with M=Mn, Fe, Co, Ni or combinations thereof). Specifically, we can determine magnetic properties such as susceptibility, magnetic structure and heat capacity. In the seminar, we will present simulated results from our B.Sc. project, which include
- Heat capacity and magnetic ground states for different compositions of LiCo1-xNixPO4
- Phase diagrams and magnetic phases when exposed to external fields.
- Neutron diffraction patterns and diffuse magnetic scattering computed from the magnetic structure.
This is compared to experimental results obtained by neutron scattering. We will also give a short introduction to our current work on developing a more versatile code, which can be applied to a wide range of systems, and not just Lithium Orthophosphates.
