Thickness-Dependent Spintronic Terahertz Emission in MBE-Grown PtTe: From Semiconductor to Type-II Dirac Semimetal
Rahul Sharma, Sylvain Massabeau, Armando Pezo +13
Spintronic terahertz (THz) emitters have established themselves as among the most practical broadband THz sources available, yet their performance remains fundamentally limited by…
Unconventional views on orbitronics supported by experimental results
Melissa Yactayo, A. Pezo, J. L. Ampuero +9
Emerging orbitronics assumes long-range orbital current transport, analogous to spin currents. However, recent theory and experiments challenge this view, showing rather local char…
Orbital torque and efficient magnetization switching using ultrathin Co|Al light-metal interfaces: Experiments and modeling
N. Sebe, A. Pezo, S. Krishnia +5
The emergence of the orbital degree of freedom in modern orbitronics offers a promising alternative to heavy metals for the efficient control of magnetization. In this context, ide…
Anatomy of torques from orbital Rashba textures: the case of Co/Al interfaces
A. Pezo, N. Sebe, A. Manchon +2
In the context of orbitronics, the rising of the orbital angular momentum generated at light metal interfaces from orbital textures via orbital Rashba-Edelstein effects nowadays re…
Inverse Rashba-Edelstein THz emission modulation induced by ferroelectricity in CoFeB/PtSe2/MoSe2//LiNbO3 systems
S. Massabeau, O. Paull, A. Pezo +10
Spintronic Terahertz emitters, based on optically triggered spin-to-charge interconversion processes, have recently emerged as novel route towards compact and efficient THz sources…
Spin and Orbital Rashba effects at the Ni/HfO interface
Armando Pezo, Andrés Saul, Aurélien Manchon +1
We predict the giant ferroelectric control of interfacial properties of Ni/HfO2, namely, (i) the magnetocrystalline anisotropy and (ii) the inverse spin and orbital Rashba effects.…
