Applied Physics and Mathematics Annotation << Back MAGNETIC FLUX QUANTUM PRODUCED BY ELECTRON SPIN V.D. PAVLOV It is noted that attributing a quantum ћ of kinetic momentum to a Cooper pair of electrons is unacceptable. Therefore, the formula for the quantum of magnetic flux from a Cooper pair is equally unacceptable. In reality, there is a quantum of F. London, a quantum of magnetic flux caused by the electron spin, and their superposition (quasi-quantum). It (quasi-quantum) was measured in 1961. Keywords: electron, Cooper pair, quantum of kinetic moment, quantum of magnetic flux, quantum of F. London, spin, superposition, quasiquantum. DOI: 10.25791/pfim.03.2025.1333 Pp. 17-19.
