Accounting the size distribution of HTS granules for the critical current density from magnetic measurements
D. M. Gokhfeld, Yu. S. Gokhfeld
The determination of the critical current density from magnetic hysteresis loops is widely used to characterize and compare superconducting samples. Magnetic hysteresis loops for t…
Larger grains in high-Tc superconductors synthesized by the solid-state reaction route
D. M. Gokhfeld, M. I. Petrov, S. V. Semenov +4
Solid-state synthesis is widely used in exploratory research to study various structural modifications that affect the properties (critical temperature, critical current density, i…
Spontaneous rotation of magnets levitating above high-Tc superconductor
D. M. Gokhfeld, S. Yu. Shalomov, D. B. Sultimov +1
The levitation of a cylindrical permanent magnet over a high-temperature superconductor cooled by liquid nitrogen can be accompanied by spontaneous oscillations and rotation. The r…
Magnetic flux trapping in porous superconductors
Denis Gokhfeld
The magnetization of superconducting samples is influenced by their porosity. In addition to structural modifications and improved cooling, the presence of pores also plays a role…
Surface barrier of holes drilled in a type-II superconductor
Denis Gokhfeld
Holes drilled in a type-II superconductor trap the magnetic flux. Following Clem's flux pinning model, we consider surface pinning as a mechanism for compressing the magnetic flux…
Anisotropy and crystallite misalignment in textured superconductors
D. M. Gokhfeld, S. V. Semenov, M. I. Petrov +2
A misalignment of anisotropic crystallites causes small values of anisotropy and decreases the critical current density of textured polycrystalline superconductors. To relate the c…
