Description
The possibility to tailor geometries and lattices of nanosized magnetic elements allows one to design close to arbitrary types of magnetic metamaterials. Here we will address the magnetic properties of 2DXY mesospins, having hexagonal and square lattice arrangement. We will investigate the thermally induced order-disorder phase transitions for a range of interactions by altering the lattice distance. As well as the internal spin dimensionality of the circular islands (2&3D), showing that both the strength of the interaction between the elements and symmetry play an important role for the obtained collective order. We will also discuss the possibility of using XRMS for obtaining information on the magnetic correlations by exploiting reciprocal space in 2DXY systems.
