Heuristic Description of Magnetoelectricity of Cu<sub>2</sub>OSeO<sub>3</sub>
CuO<sub>2</sub>SeO<sub>3</sub> is
an insulating material that hosts topologically nontrivial spin whirls,
so-called skyrmions, and exhibits magnetoelectric coupling allowing
to manipulate these skyrmions by means of electric fields. We report
magnetic force microscopy imaging of the real-space spin structure
on the surface of a bulk single crystal of CuO<sub>2</sub>SeO<sub>3</sub>. Based on measurements of the electric polarization using
Kelvin-probe force microscopy, we develop a heuristic description
of the magnetoelectric properties in CuO<sub>2</sub>SeO<sub>3</sub>. The model successfully describes the dependency of the electric
polarization on the magnetization in all magnetically modulated phases
