User Software for Numerical Study of Josephson Junction with Magnetic Momenta

Abstract

Abstract.A user software for numerical study of a Josephson junction model with magnetic momenta is presented. Computer implementation has been done by means of Wolfram Mathematica using the extensive capabilities of this system to create interactive dynamic objects. Two methods for numerical solution of the respective system of ordinary differential equations are implemented: the four-step Runge-Kutta algorithm and the Runge-Kutta-Fehlberg method with predetermined accuracy. Results of numerical simulation are presented to confirm the correctness of the calculations done with the developed software.

“…e-mail: stefani.panaiotova93@gmail.com e-mail: bashashinmv@jinr.ru This contribution aims at studying the magnetic reversal effect in a wide range of parameters of the φ 0 -JJ model. As in our previous works [3], [4], [5], we consider the system of the "superconductor -ferromagnet -superconductor" Josephson junction (SFS JJ), schematically shown in Fig. 1 reproduced from [4].…”

The three spatial components m x , m y , m z denote the projections of the magnetic moment M along the x-, y-, z-axes, respectively.…”
