Domain-engineered ferroelectric BiFeO thin films for efficient bias-free THz emission
Z. Abdul Hadi, N. Rezi, M. Monti +10
Ultrashort light pulses can drive transient photocurrents in solids, the basis of modern terahertz (THz) emitters. Ferroelectrics have recently emerged in this context as sources t…
Reprogrammable magnonic logic in a multiferroic heterostructure via magnetoelectric coupling
Ping Che, Amr Abdelsamie, Ádám Papp +14
The realization of fully reconfigurable, voltage-controlled, and programmable on-chip magnonic devices is essential to fully harness the potential of spin waves for signal processi…
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…
