Ginzburg-Landau equations. Zavaritskii’s experiments. Low-temperature films. Hypothesis about a large G-L parameter. Type II superconductors. Upper critical field and the order parameter in its vicinity. Nodes in the plane perpendicular to the magnetic field and the behaviour of the phase, as the only way of compensation of the growth of the vector potential. Quantum vortices. First critical field. Vortex lattice. Bulk magnetization. Experiments with superconducting alloys (de Haas, Shubnikov). Experimental confirmation of the vortex lattice and final recognition of the theory. Some other works. Theory of high-Tc superconductors.
Professor Abrikosov will receive an honorary degree from Loughborough University on 8 July.
