摘要：
Within the framework of the modified theory of Ferrell-Prange examine the effect of a weak external magnetic field on the superconducting Josephson's unharmonic nanocontacts type. Defined the coordinate dependence of the difference of phase phi(x), superconducting current I-s(x) and the magnetic field H(x) in unharmonic nanocontacts. Revealed, if increase the value of the unharmonism then parameter of phase fades quickly and the depth of penetration of the magnetic field decreases. Shown, that viewed unharmonic contacts passive react to external magnetic field than harmonic contacts.
