Hopf bifurcation and stochastic spiking in an antiferromagnetic FitzHugh--Nagumo normal form
D. Maroulakos, A. Wal, I. Tralle +2
Antiferromagnets offer ultrafast, stray-field-free dynamics that are attractive for neuromorphic spintronic devices. Here we analyze an antiferromagnetic spin-Hall nano-oscillator…

Effective masses, Burstein-Moss shift, and bandgap renormalization in degenerate Al-doped ZnO from broadband ellipsometry and Hall measurements
S. Mishra, L. A. Enrique, D. Cespedes +7
A comprehensive methodology is developed to extract electron and hole effective masses in degenerate semiconductors through a simultaneous global fit of carrier concentration depen…

On the crystalline environment of luminescent Tb ions embedded in indium tin oxide thin films: a DFT and Crystal field analysis assessment
E. Serquen, K. Lizárraga, L. A. Enrique +6
We assess the local symmetry and crystal environment of trivalent terbium ions embedded in an indium tin oxide (ITO) matrix with bixbyite structure. The \mbox{Tb} ions tend…
