Molecular dynamics simulations of body-centered cubic (bcc) iron thin films with crack defects were carried out by adopting methods EAM (Embedded Atom Method) potential, spin/exchange potential and spin/neel potential. In this article, the effects variation distance between two their directions on magnetostrictive properties are studied, corresponding microscopic mechanism is also analyzed. The results show that affect atomic magnetic moment nearby, vary direction spacing defects. If defect...
Defects are an inevitable occurrence during the manufacturing and use of ferromagnetic materials, making it crucial to study microscopic mechanism magnetostrictive properties materials with defects. This paper conducts molecular dynamics simulations on low-dimensional iron thin films containing hole or crack defects, analyzes compares impact defect size properties, investigates their effects. The results indicate that saturation strains models do not increase monotonically as increases....
