   Abstract : Abstract In this thesis, the high temperature superconductors (HTSC) La2CuO4+x and Bi2Sr2CaCu2O8+d and the colossal magnetoresistive (CMR) La1-xSrxMnO3 have been studied by photoelectron spectroscopy. Techniques such as angular resolved photoemission (ARPES), resonant photoemission spectroscopy (RESPES) and x-ray absorption spectroscopy have been applied, using synchrotron radiation. READ MORE

5. 3. Structure and physical properties of doped 123-superconductors and search for new superconducting hydrides

   Author : Pieter Lundqvist; KTH; []
   Keywords : ;

   Abstract : The field of high temperature superconductors (HTSC) isstill controversial. The difficulty to explain the high Tcvalues as well as other anomalous superconductingand normal state properties of the HTSC’s necessitatesfurther studies and search for empirical relations in the largeamount of collected data.

6. 4. A study on nanophase functional materials : high Tcsuperconductors and Zinc Oxide

   Author : Lingna Wang; KTH; []
   Keywords : ;

   Abstract : Nanophase materials are an active materials research topicthat has received a great deal of attention over the past fewyears. Tlus mesis deals mainly with the synthesis, processing,and characterization of nanophase functional materials. Twotypes of functional materials were considered: high temperaturesuperconducting oxides (HTSC) and Wnc oxide. READ MORE
