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…

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…
