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…
Strain-induced polarization rotation in freestanding ferroelectric oxide membranes
Alban Degezelle, Razvan Burcea, Pascale Gemeiner +7
Freestanding ferroelectric membranes have emerged as a versatile tool for strain engineering, enabling the exploration of ferroelectric properties beyond traditional epitaxy. The r…
Band gap tuning by structural phase transition in Sm-substituted BiFeO3 powders
Christina Hill, Michele Melchiorre, Cosme Milesi-Brault +6
The substitution of bismuth by samarium in BiFeO3 is known to induce a structural phase transition from the polar phase to a non-polar phase, with a possible antiferroelectric inte…
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…
