【 摘 要 】

The work considers the influence of weak external magnetic field on anharmonic Josephson's nanocontacts. The coordinate dependences of phase differences φ(x), superconducting current Is(x) and magnetic field H(x) anharmonic nanocontacts were found. It was defined the anharmonism parameter increase leads to phase difference φ(x) decaying faster, and penetration of magnetic field decreases. It was shown the considered contacts react on external weak magnetic field in more passive way.
