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…
Spin and Orbital Rashba response in ferroelectric polarized PtSe/MoSe/LiNbO heterostructures
Armando Pezo, Sylvain Massabeau, Filip MiljeviÄ +6
Recent studies using Terahertz Time-Domain Spectroscopy (THz-TDS) with spintronic emitters as a source have revealed distinct signatures of the Rashba effect. This effect, which ar…
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…
Theory of spin and orbital charge conversion at the surface states of Bi_{1-x}Sb_x topological insulator
Armando Pezo, Jean-Marie George, Henri Jaffrès
Topological insulators are quantum materials involving Time-reversal protected surface states(TSS) making them appealing candidates for the design of next generation of highly effi…
