Abstract
Periodic structure of the magnetization reversal domains is studied within the superconductor–ferromagnetic–superconductor φ0-junction model. The model is described by the Cauchy problem for the system of nonlinear ordinary equations which is numerically solved by means of the 2-step Gauss–Legendre method. Two versions of parallel implementation on the basis of MPI and OpenMP techniques have been developed. Efficiency of both versions is confirmed by test calculations. An effect of frequency of ferromagnetic resonance on the configuration MR domains has been investigated. The calculations have been performed at the HybriLIT Platform of the JINR’s Multifunctional Information and Computing Complex.
