  1. 1. Spin-Glass Behaviour in Ordered Solids

    University essay from Uppsala universitet/Materialteori

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

    Abstract : 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

  3. 2. Lithium-ion Behaviour in Hard Carbon Anodes: Insights from 7Li NMR Spectroscopy

    University essay from KTH/Kemi

    Author : Adina Landström; [2023]
    Keywords : NMR spectroscopy; hard carbon; anode; lithium-ion battery; spin relaxation; NMR-spektroskopi; hårt kol; anod; litiumjonbatteri; spinnrelaxation;

    Abstract : Litiumjonbatterier (LIB) är viktiga komponenter i dagens teknologi och används för att driva en mängd olika elektroniska system, allt från datorer och mobiltelefoner till bilar och flygplan. Eftersom efterfrågan på effektiv energilagring fortsätter att växa finns ett fortsatt behov för forskning och utveckling inom området. READ MORE

  4. 3. CHARACTERIZATION AND EVALUATION OF A NIPAM POLYMER GEL MRI DOSIMETER SYSTEM

    University essay from

    Author : Christian Waldenberg; [2022-11-08]
    Keywords : Medical physics; Normoxic polymer gel dosimeter; NiPAM;

    Abstract : Purpose: The normoxic polymer gel dosimeter based on N-isopropyl acrylamide (NiPAM) is a promising full 3D-dosimeter with high spatial resolution and near tissue equivalency. However, limited work have been done in vestigating this dosimeter. The dose response and reproducibility of a NiPAM dosimeter was investigated. READ MORE

  5. 4. Low-dimensional Magnetism in Novel 2D Honeycomb Materials

    University essay from KTH/Tillämpad fysik

    Author : Sebastian Johnsen; [2021]
    Keywords : Applied physics; Materials physics; Quantum materials; Magnetism; Muons; Neutrons; Tillämpad fysik; Materialfysik; Kvantmaterial; Magnetism; Myoner; Neutroner;

    Abstract : A Kitaev quantum spin liquid is a phase of matter predicted to host excitations that can be used to preform fault-tolerant quantum computation. Though the theoretical prediction of such a state is on firm footing, its realisation in real materials has proven to be elusive. READ MORE

  6. 5. Making Hypervelocity Stars

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Frans Forsberg; [2020]
    Keywords : Stellar Dynamics; Binary Stars; Galactic Centre; Binary Relaxation; Physics and Astronomy;

    Abstract : In this thesis, I investigate if the binaries that are being tidally disrupted by means of the Hills mechanism, producing hypervelocity stars, could have been transported to the galactic centre by two-body scattering. To survive a scattering event, the binary must be hard, meaning that the binding energy of the binary is higher than the kinetic energy of the collider. READ MORE
