Manipulating the shape of flexible magnetic nanodisks with meronlike magnetic states

The control of the magnetic properties shapeable devices and manipulation flexible structures by external fields is a keystone future magnetoelectronics-based devices. This work studies elastic magnetoelastic nanodisc that hosts meron as state can be deformed from with positive to negative Gaussian curvature. We show winding number hosted crucial determine curvature sign stable obtained shape. Additionally, we optimum reached depends on geometrical mechanical parameters. It shown an increase in radius, thickness, Young's modulus lead decrease absolute value. Finally, it nanodisc's shape also connection between polarity chirality vortex-like meron.
