The magnetic field (H) -temperature (T) phase boundary has been measured for mesoscopic superconducting samples of different topology (lines, loops and dots). Both the quantization effects and the slope of the Hc(T) line are fiflly governed by the confinement geometry. As a result, "quantum design"
Distortions of the layers in layered superconductors result in a decrease of the critical magnetic field. The distortions have the greatest influence when the field is applied at small angles to the layers. The critical field is calculated in the limits of large and small distortions. When the size
