1. 1. Magnetic materials with tunable thermal, electrical, and dynamic properties : An experimental study of magnetocaloric, multiferroic, and spin-glass materials

   Författare :Matthias Hudl; Per Nordblad; DD Sarma; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetocalorics; multiferroics; spin glasses; magnetization; polarization; spin-dimensionality; Fasta tillståndets fysik; Solid State Physics;

   Sammanfattning : This thesis concerns and combines the results of experimental studies of magnetocaloric, multiferroic and spin-glass materials, using SQUID magnetometry as the main characteriza-tion technique. The magnetocaloric effect offers an interesting new technology for cooling and heating applications.

3. 2. Collective properties of magnetic mesospins

   Författare :Erik Östman; Björgvin Hjörvarsson; Vassilios Kapaklis; Nicolas Rougemaille; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial spin ice; magnetic nano-structures; mesoscopic spin systems; mesospins; mixed spin dimensionalities; interaction modifier; engineering of energy landscape; emergence;

   Sammanfattning : Mesoscopic spin systems consist of an ensemble of lithographically patterned nanomagnetic elements - mesospins. The interactions between the mesospins, can be designed at will by altering their lateral arrangement, enabling the study of collective magnetic order in a wide range of systems. LÄS MER
