Optimizing spin-based terahertz emission from magnetic heterostructures
Francesco Foggetti, Francesco Cosco, Peter M. Oppeneer +4
Terahertz radiation pulses can be generated efficiently through femtosecond laser excitation of a ferromagnetic/nonmagnetic heterostructure, wherein an ultrafast laser-induced spin…

Phonon-tunable THz magnonic emission in multiferroic heterostructures
Sylvain Massabeau, Amr Abdelsamie, Florian Godel +13
Collective excitations such as magnons and polar phonons provide natural access to the terahertz (THz) regime, but efficient generation and tunability remain elusive. Multiferroic…

Large Chiral Orbital Texture and Orbital Edelstein Effect in Co/Al Heterostructure
Sergey A. Nikolaev, Mairbek Chshiev, Fatima Ibrahim +6
Recent experiments by S. Krishnia et al., Nano Lett. 23, 6785 (2023) reported an unprecedentedly large enhancement of torques upon inserting thin Al layer in Co/Pt heterostructure…
