In magnetic heterostructures ultrashort laser excitation can effectively generate spin dynamics and charge currents which results in THz emission. Using THz emission spectroscopy as an ultrafast contactless ammeter we study the THz emissivity in Co/Pt. The spin-charge conversion effect, known as inverse-spin-Hall effect, is a dominant source for THz emission while the spin-dependent photogalvanic effect is a much weaker source which is very sensitive to the interface properties. Using a double pump pulse approach, THz emission can be used as a probe to study the laser-induced first-order magnetic phase transition in FeRh/Pt and FeRh/Au where a latency between the initial laser excitation and the emergence of a net magnetization was observed. In Tb/Co ferrimagnet multilayers, we demonstrate the ability to switch the magnetization direction with a single laser pulse, known as single shot all optical switching. The all optical switching was confirmed as well in a Tb/Co based magnetic tunnel junction electrode after annealing at 250 degrees Celsius, represented the first initial steps towards the development of spintronic photonic hybrid magnetic memory devices.","Radboud University, 07 september 2021","Promotores : Rasing, T.H.M., Kimel, A.V.
