Abstract

The effect of strains on ferromagnetic particles has been studied. Arrays of Ni microparticles of different shapes on glass substrates have been fabricated. The magnetic state of the fabricated particles as a function of the degree of glass substrate bending has been investigated. It has been established that the ground state of unbent particles is vortex. It is shown that the substrate bending leads to the transition from the vortex to quasi-homogeneous state.
