Main Activity: 
  • Studies of high-Tc superconductors
  • Description :
    • At this time there is no webpage encompassing
      superconductivity-related activities at the Institute. Therefore,
      the following brief description is provided here:
    • There are two small groups in the Institute, dealing with 
      various aspects of basic research into superconductors.
    • The main interest has been oriented towards experiment 
      and theory of magnetic properties of high-Tc materials 
      (in recent years in particular bulk melt-textured and 
      single-crystalline RE-123 materials, BiSCCO tapes, 
      thin film structures), vortex pinning on various kinds 
      of defects under various conditions, magnetic relaxation, 
      modeling and interpretation of magnetization curves, 
      magnetic flux motion in mesoscopic thin film 
      structures, granularity-induced anomalies in magnetisation 
      processes, methodology of magnetic measurements of 
      superconductors, Hall effect, mixed state Hall effect in 
      multiphase superconductors, superconductor response 
      to extremely low magnetic fields: observation of 
      sequence of transitions from 2D to 3D superconducting 
      state in YBa2Cu3O6+x single crystals etc. Electric field 
      in superconductors, charge profile in vortices, Bernoulli 
      potential at a superconductor surface, and other associated
       topics have been treated theoretically, as well as vortex 
      pinning on large defects.
    • Permanent staff consists at the moment of 5 senior scientists 
      directly involved in the above mentioned research 
      (Z. Janu, M. Jirsa, J. Kolacek, P. Lipavsky, V. Zelezny), 
      some others dealing with superconductivity occasionally, 
      two doctoral students.
    • Experimental set-ups available: 
      Two fully equipped PPMS machines (9 and 14 Tesla), with 
      extraction, vibrating sample (VSM), and torque magnetometers, 
      transport measurements, heat capacity option, a separate VSM 
      to 3 Tesla, two commercial SQUIDs to 5 and 7 Tesla, 
      special SQUID to extremely low magnetic fields
    • Collaborations:
