1. 11. Exploring the Magnetism of Ultra Thin 3d Transition Metal Films

   Författare :Cecilia Andersson; Olof Karis; Dimitri Arvanitis; Chi-Chang Kao; Uppsala universitet; []
   Nyckelord :Physics; thin film; xmcd; xrms; exafs; anisotropy; magnetism; Fe; Ni; Co; Ag; Cu; Fysik;

   Sammanfattning : In this thesis the magnetic and structural properties of ultra-thin 3d transition metals films have been investigated, in particular Fe, Ni and Co films. X-ray Magnetic Circular Dichroism (XMCD) has provided element specific spin (ms ) and orbital (ml ) moments per atom by utilizing the magneto optic sum-rules. LÄS MER

3. 12. Synthesis and characterization of two- and three-dimensional nanolaminated carbides

   Författare :Quanzheng Tao; Johanna Rosén; Per O A Persson; Amit Keren; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis is focused towards the synthesis and characterization of novel nanolaminated materials in primarily bulk (powder) form. Of particular interest is magnetic materials, or laminates that can be used as precursor for two-dimensional (2D) materials. LÄS MER

4. 13. Probing quantum criticality in heavy fermion CeCoIn5

   Författare :Akash Khansili; Andreas Rydh; Venkata Kamalakar Mutta; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Strongly correlated electron systems; heavy fermion; quantum criticality; Physics; fysik;

   Sammanfattning : Understanding the low-temperature properties of strongly correlated materials requires accurate measurement of the physical properties of these systems. Specific heat and nuclear spin-lattice relaxation are two such properties that allow the investigation of the electronic behavior of the system. LÄS MER
