Considerable enhancement of the critical current in a superconducting film by a magnetized magnetic strip

Institute for Physics of Microstructures, Russian Academy of Sciences, 603950, Nizhny Novgorod, GSP-105, Russia(Dated: February 2, 2008)We show that a magnetic strip on top of a superconducting strip magnetized in a specifieddirection may considerably enhance the critical current in the sample. At fixed magnetization of themagnet we observed diode effect - the value of the critical current depends on the direction of thetransport current. We explain these effects by a influence of the nonuniform magnetic field inducedby the magnet on the current distribution in the superconducting strip. The experiment on a hybridNb/Co structure confirmed the predicted variation of the critical current with a changing value ofmagnetization and direction of the transport current.

the SP state with a vortex does not exist and it transforms to 2D nucleus state, which is a finite region with partially suppressed order parameter. It is also shown that for slightly lower currents the contribution of the vortex core energy is important for SP state with a vortex and it cannot be neglected for

. It is demonstrated that in the film with local current concentration near the bend the energy of SP state may be much smaller than one in the straight film and it favors the effect of fluctuations in such a samples.
