  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. Internal strain in the magnetocaloric alloy MnCoSi

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Olivia Vaerst; [2021]
    Keywords : MnCoSi; Magnetocaloric Effect; Arc Melting; Strain; X-Ray Diffraction; Williamson-Hall; Rietveld Refinement; Physics and Astronomy;

    Abstract : Cooling systems based on magnetic refrigeration are a promising and environmentally friendly alternative to commonly used gas-compression refrigeration. Magnetic refrigeration is based on the magnetocaloric effect. READ MORE

  4. 3. Quantum statistics and the magnetocaloric effect

    University essay from Uppsala universitet/Materialteori

    Author : Anna Sandberg; [2020]
    Keywords : quantum statistics; magnetocaloric effect; magnetocaloric; magnetic cooling; simulation;

    Abstract : Caloric materials show prospect in replacing the function of vaporcompression systems in todays cooling devices, resulting in more energy efficient cooling and eliminating the need for refrigerents which contribute to climate change. This project has focused on magnetocaloric materials, which experience changes in temperature when exposed to magnetic fields. READ MORE

  5. 4. Tuning the Curie temperature and phase fraction of FeNi25-based alloys with Mn and Co for magnetocaloric applications

    University essay from KTH/Materialvetenskap

    Author : Marie Sanglé-Ferrière; [2020]
    Keywords : Thesis; magnetocaloric effect; Curie temperature; FCC; FeNi25; Avhandling; magnetokalorisk effekt; Curie-temperatur; FCC; FeNi25;

    Abstract : This paper discusses the search of an FeNi25-based alloy with a face-centered cubic crystal structure exhibiting a Curie point around room temperature, for magnetocaloric applications. Fe was substituted in various amounts with FCC-stabilising elements Mn and Co as these elements respectively decrease and increase the Curie Temperature, thus enabling to tune the Curie point.

  6. 5. Setup Implementation for a Direct Measurement Technique of the Magnetocaloric Effect

    University essay from KTH/Materialvetenskap

    Author : Ferdinand Posva; [2020]
    Keywords : Magnetocaloric effect; Direct method; Gadolinium; High entropy alloys;

    Abstract : This project presents an attempt to construct a setup and implement a reliable technique for measuring the magnetocaloric effect (MCE) on various materials via a direct method for the acquisition of the data. The main objective of the latter is to produce a ∆Tadiabatic vs T graph over a reasonable temperature span (-100◦C up to 220◦C) by thermal monitoring of a magnetic material exposed to an oscillating magnetic field with a maximum strength of 1.
