1. 1. The Magnetocaloric Effect in Antiferromagnetic and Noncollinear Magnets

   University essay from Uppsala universitet/Materialteori

   Author : Siri Alva Berge; [2023]
   Keywords : magnetocaloric effect; atomistic spin dynamics; monte carlo; antiferromagnet; neodymium; noncollinear magnetism;

   Abstract : The magnetocaloric effect (MCE) is the temperature change in a magnetic material due to a change in an applied magnetic field. How the MCE behaves in different magnetic materials and at different phase transitions is fundamental to understand. READ MORE

3. 2. Influence of Superconducting Order Parameter on Quasi-Particle Interference

   University essay from Uppsala universitet/Materialfysik

   Author : Siri Alva Berge; [2022]
   Keywords : ;

   Abstract : Superconductors are important to study due to their many applications. Superconductivityarises when electron pairs, so-called Cooper pairs, form in the material.To understand the mechanism behind the formation of the Cooper pairs, the pairingsymmetry, described by the order parameter, must be found.

4. 3. Phase Diagrams of Finite Spin Chains with Coupled Spin and Lattice Vibrations

   University essay from Uppsala universitet/Materialteori

   Author : Siri Alva Berge; [2021]
   Keywords : spin-lattice coupling; spin-vibration coupling; Heisenberg exchange; magnetism;

   Abstract : The spin-lattice coupling is due to itinerant electrons interacting with both spins of ions and phonons, mediating a coupling between magnetic spin moments and lattice vibrations. In this project, the coupling is studied systematically for finite quantum spin chains of size 2 – 10. READ MORE
