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…

Terahertz antiferromagnetic dynamics induced by ultrafast spin currents
Sanjay René, Artem Levchuk, Amr Abdelsamie +10
Insulating antiferromagnets are anticipated as the main protagonists of ultrafast spintronics, with their intrinsic terahertz dynamics and their abililty to transport spin informat…
