The magnetic field associated with a picosecond intense electron pulse is\nshown to switch locally the magnetization of extended films and nanostructures\nand to ignite locally spin waves excitations. Also, topologically protected\nmagnetic textures such as skyrmions can be imprinted swiftly in a sample with a\nresidual Dzyaloshinskii-Moriya spin-orbital coupling. Characteristics of the\ncreated excitations such as the topological charge or the width of the magnon\nspectrum can be steered via the duration and the strength of the electron\npulses. The study points to a possible way for a spatiotemporally controlled\ngeneration of magnetic and skyrmionic excitations.\n
