Collective Smart Вehaviour of Magnetic Nanoparticles at Simulation of Hysteresis Phenomena in Artificial Ordered Array

Abstract:

The high performance algorithm for supercomputer simulation of magnetic nanoparticles arrays was elaborated and implemented in parallel c++ code. Our program package allows a modeling of magnetic hysteresis phenomenon in the system of the magnetic spherical monoaxial one-domain dipole nanoparticles fixed in node of a square lattice with the period of 10^-8 m in frame of Stoner-Wolfforth approach. During numerical experiments dependences of a type of curves of a hysteresis on number of particles and values of a critical field are investigated. It was showed, that the area of loops has proportional dependence from individual critical field of nanoparticles.
