Abstract: The article describes the basics of both: the modeling of current transport through the Josephson heterostructures with ferromagnetic and normal bi-channel as weak link of arbitrary topology and the analysis of its current-phase relation. We propose a method to create φ-contacts on the base of such Josephson heterostructures with NF bi-channel and to realize promising φ-cells with built-in frustration. We analyze the parameters of such elementary cells containing φ-contacts.

Key words: Josephson effect, magnetic Josephson junction, current-phase relation.
