   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. Magnetism of manganites, semiconductors and spin glasses

   Author : Roland Mathieu; Ian Campbell; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; fasta tillståndets fysik; Solid State Physics;

   Abstract : Magnetic and electrical properties of selected compounds containing manganese (Mn) are investigated by SQUID magnetometry and transport measurements.(Ga,Mn)As is a magnetic semiconductor obtained from GaAs by substituting Ga3+ for Mn2+. Mn acts in the alloy as a magnetic impurity, as well as a hole dopant. READ MORE
