1. Spin-Glass Behaviour in Ordered Solids
University essay from Uppsala universitet/MaterialteoriAbstract : The spin-glass is a peculiar magnetic phase, exhibiting non-trivial dynamics at low temperatures, characterized by an continuously evolving state without long-range order. The behavior requires some degree of disorder to occur, often in the way of impurities or random exchange energy between the spins. READ MORE

2. The Magnetocaloric Effect in Antiferromagnetic and Noncollinear Magnets
University essay from Uppsala universitet/MaterialteoriAbstract : 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. Accelerating longitudinal spinfluctuation theory for iron at high temperature using a machine learning method
University essay from Linköpings universitet/Teoretisk FysikAbstract : In the development of materials, the understanding of their properties is crucial. For magnetic materials, magnetism is an apparent property that needs to be accounted for. There are multiple factors explaining the phenomenon of magnetism, one being the effect of vibrations of the atoms on longitudinal spin fluctuations. READ MORE

4. Investigations of domain-wall motion using atomistic spin dynamics
University essay from Uppsala universitet/MaterialteoriAbstract : In this thesis, current driven domain-wall motion is studied using atomistic simulations with the exchange coupling modeled by the Heisenberg Hamiltonian under the nearest-neighbor approximation. The investigations may be divided into two parts, each concerned with how different aspects of the systems affect the domain-wall motion. READ MORE
