Sample width dependence of the skyrmion phase diagram in the plane of temperature and magnetic field. Panels (a)–(c) are all composed of three parts: sparse skyrmion chains in the FeGe stripe with varied width at low temperature T = 100 K obtained as magnetic field is changed; packed skyrmions in corresponding samples at high temperature T = 220 K; sample width dependence of the skyrmion phase diagram in the plane of temperature and magnetic field.
