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, 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 -
