1. 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

2. Internal strain in the magnetocaloric alloy MnCoSi
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : 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

3. Quantum statistics and the magnetocaloric effect
University essay from Uppsala universitet/MaterialteoriAbstract : 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

4. Tuning the Curie temperature and phase fraction of FeNi25-based alloys with Mn and Co for magnetocaloric applications
University essay from KTH/MaterialvetenskapAbstract : 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.

5. Setup Implementation for a Direct Measurement Technique of the Magnetocaloric Effect
University essay from KTH/MaterialvetenskapAbstract : 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.
