Single-shot all-optical magnetization switching in in-plane magnetized magnetic tunnel junction
S. Geiskopf, J. Igarashi, G. Malinowski +6
Single pulse All Optical Helicity-Independent Switching is demonstrated in an in-plane magnetized magnetic tunnel junction. A toggle switching of the 2nm thick Co40Fe40B20 soft lay…
