Programme

The Symposium is going to address new oxide materials - namely these exhibiting high- T c superconductivity (HTSC) and colossal magnetoresistance (CMR), as well as ferromagnetic oxide semiconductors and magnetic oxide nanoparticles. The phenomena of HTSC and CMR, especially their microscopic mechanisms, are still hot topics in the solid state physics. In spite of the very intensive studies performed by the best research groups in the field - both phenomena are not fully understood. In materials exhibiting both of these phenomena, the co-existence of various structural, magnetic, charge and orbital states is observed, due to strong electron-electron and electron-lattice couplings. The so called parent compounds for these two groups of materials are antiferromagnetic insulators and compounds exhibiting HTSC or CMR are obtained by proper doping of them. In both groups of materials characteristic phenomena are associated with spatial inhomogeneity related to coexistence of different phases, known as the phase separation. The phase separation manifests itself in formation of phases with different magnetic and conductive properties. By using chemical doping or applying external factors, e.g., light, pressure, and ionizing radiation, various ground states of oxides materials can be realized and various fascinating collective phenomena can be observed. Ferromagnetic oxide semiconductors, magnetic oxide nanoparticles, as well as, materials exhibiting HTSC and CMR can be used in the new technologies for production of sensors of new generation, for information storage and for production of heterostructures needed for spintronics.

The main topics of the Symposium will be:

  • fabrication and studies of thin films and heterostructures of HTSC and CMR materials
  • nature of superconductivity in strongly correlated systems and search of new superconducting materials
  • ferromagnetic oxide semiconductors
  • magnetic oxide nanoparticles
  • studies of the mixed state in HTSC and in other superconductors relevant to the applications
  • magnetic and transport properties of CMR materials
  • studies of phase separation in HTSC and CMR materials
