Chapter 1 “Fluctuoscopy” of Superconductors
A.A. Varlamov
Abstract Study of .uctuation phenomena in superconductors (SCs) is the subject of great fundamental and practical importance. Understanding of their physics allowed to clear up the fundamental properties of SC state. Being predicted in 1968, one of the .uctuation effects, namely paraconductivity, was experimentally observed almost simultaneously. Since this time, .uctuations became a noticeable part of research in the .eld of superconductivity, and a variety of .uctuation effects have been
