High temperature ferromagnetism in epitaxial monolayers of Co-doped Fe5GeTe2

Jules Courtin, Fatima Ibrahim, Davide Benettin +14

Magnetic van der Waals materials have mainly been investigated in their bulk form or as few-layers flakes. Due to the challenges in producing atomically thin films, only a few have…

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…

Rashba engineering at van der Waals interfaces

Rahul Sharma, Soumya Mukherjee, Fatima Ibrahim +26

Two-dimensional transition metal dichalcogenide (TMD) interfaces offer a versatile platform for studying emergent quantum phenomena and enabling novel device functionalities. When…

Frustrated out-of-plane Dzyaloshinskii-Moriya interaction and the onset of atomic-scale 3 magnetic textures in 2D FeGeXTe (X = Te, Se, S) monolayers

Rabia Caglayan, Louise Desplat, Sergey Nikolaev +5

We theoretically study the effect of in- and out-of-plane Dzyaloshinskii-Moriya interaction (DMI) on the magnetic ground states of two-dimensional (2D) FeGeXTe (X=Te, Se, S) mo…

Dzyaloshinskii-Moriya interaction chirality reversal with ferromagnetic thickness

Capucine Gueneau, Fatima Ibrahim, Johanna Fischer +10

In ultrathin ferromagnetic films sandwiched between two distinct heavy metal layers or between a heavy metal and an oxide layer, the Dzyaloshinskii-Moriya interaction (DMI) is of i…

Spin and Orbital Rashba response in ferroelectric polarized PtSe/MoSe/LiNbO heterostructures

Armando Pezo, Sylvain Massabeau, Filip Miljević +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…
