1. 1. Spin-Glass Behaviour in Ordered Solids

   Kandidat-uppsats, Uppsala universitet/Materialteori

   Författare :Erik Karpelin; [2023]
   Nyckelord :spin-glass; self-induced; variation; Edwards-Andersson; glassy;

   Sammanfattning : 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. LÄS MER

3. 2. Exploring time-extended complexity measures in magnetic systems

   L3-uppsats, Uppsala universitet/Materialteori

   Författare :Jannes van Poppelen; [2023]
   Nyckelord :;

   Sammanfattning : Complexity, a fundamental concept in physics, encompasses phenomena spanning atomic to cosmic scales. The natural emergence of complexity can be explained by self-organized criticality. In this work, two complexity measures in magnetic systems are explored. LÄS MER

4. 3. The Magnetocaloric Effect in Antiferromagnetic and Noncollinear Magnets

   Master-uppsats, Uppsala universitet/Materialteori

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

   Sammanfattning : 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. LÄS MER
