The non-trivial topological winding of skyrmions in chiral magnets distinguishes them from conventional forms of magnetic order and micromagnetic textures. This topological protection of skyrmions promises a new route to advanced non-volatile high density data storage devices. We report a detailed study of the stability and the decay of skyrmion lattices in chiral magnets when prepared in a metastable state. We consider possible decay mechanisms and discuss the underlying energy scales associated with the topological protection.
