Each phase is defined by the configuration of the magnetic moments of the chain of single domain nanomagnets and correspondingly the existence of

We have used the dynamical Landau–Lifshitz–Gilbert equations in complement to a quasi-static analysis of the complicated energy landscapes of the interacting nanomagnets. In doing so we

In the present theory, the transverse shear stresses satisfy the traction free boundary conditions of the rectangular plates and these stresses

[4] presented a trigonometric shear deformation theory with considering several unknown functions for the displacement field to study the static analysis of functionally graded plates. In this study, the effects of Pasternak and Winkler foundations were also investigated
