Abstract :
Recently a new type of magnonic crystal - Ni80Fe20 films deposited on top of periodic 2-D arrays of Ni80Fe20 submicron circular disks - was proposed [1]. In such structures the continuous film can be considered as a magnonic waveguide, when the role of dot array is to create periodic perturbations of internal fields in the neighbor regions of the film. Here we study how the change of two parameters - inter-disk distances and the thickness of the film on top of the array will affect the in-plane anisotropy of the system.
