Institute of Physics, Academy of Sciences of the Czech Republic
(Institute of Physics ASCR)

• 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, P. Vasek),
    some others dealing with superconductivity occassionally,
    three students: one undergraduate and two doctoral, and one
    postdoc.
  • 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 2 Tesla with vertical axis sample rotation option, commercial
    SQUID to 5 Tesla, Hall probe scanning set-up, a separate
     transport and Hall effect experimental set-up to 14 Tesla,
    special SQUID to extremely low magnetic fields …
