To the 85th birthday of Prof. Igor K. Yanson — Founder of the method of point-contact spectroscopy

I.K. Yanson is a well-known physicist in the field of fundamental research of electronic properties of metals, superconductivity, magnetism, and biophysics. I. K. Yanson was the first to observe electromagnetic radiation from superconducting tunnel junctions (1964), which was direct evidence for the existence of a non-stationary Josephson effect. Another important achievement was the discovery of Point-contact spectroscopy method (1974), which occupies an important place among the spectroscopic methods of solid-state physics and has become a powerful tool for studying the interaction of conduction electrons with the different types of quasiparticle excitations in metallic systems. I. K. Yanson made significant contribution to nanophysics and study of atomic-size contacts.
