  1. 6. Best practice of extracting magnetocaloric properties in magnetic simulations

    University essay from Uppsala universitet/Materialteori

    Author : Johan Bylin; [2019]
    Keywords : Magnetocaloric effect; Thermodynamics; Statistical mechanics; Monte Carlo simulations; Metropolis algorithm; Wang-Landau method; Isothermal change in entropy; Adiabatic change in temperature; Numerical methods; Effective spin models;

    Abstract : In this thesis, a numerical study of simulating and computing the magnetocaloric properties of magnetic materials is presented. The main objective was to deduce the optimal procedure to obtain the isothermal change in entropy of magnetic systems, by evaluating two different formulas of entropy extraction, one relying on the magnetization of the material and the other on the magnet's heat capacity.

  3. 7. Magnetic Properites in Alloy Systems

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Nanny Strandqvist; [2017]
    Keywords : Magnetocaloric effect; adiabatic temperature change; magnetic entropy change; magnetocaloric materials; magnetic refrigerator;

    Abstract : The attention for materials displaying high magnetocaloric effect (MCE) has grown during the past 30 years. One of the most important properties of MCE is the adiabatic temperature change ( ). The main aim of this work was to develop a method to measure the temperature change ( ) for magnetocaloric materials in a changing magnetic field. READ MORE

  5. 9. Assessment of magnetic cooling for domestic applications

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Ivan Montenegro Borbolla; [2012]
    Keywords : magnetic cooling model simulation assessment domestic applications;

    Abstract : Magnetic cooling is an emerging refrigeration technology with potential to surpass the performance of vapour compression devices. It has been successfully applied in the cryogenic temperature ranges, where magnetic cooling gas liquefiers surpass the performance of conventional liquefaction systems. READ MORE
