Pressure-induced collapse of ferromagnetism in Nickel
A. Ahad, M. S. Bahramy
Transition metals, Fe, Co and Ni, are the canonical systems for studying the effect of external perturbations on ferromagnetism. Among these, Ni stands out as it undergoes no struc…
Berry curvature generation detected by Nernst responses in ferroelectric Weyl semimetal
Cheng-Long Zhang, Tian Liang, M. S. Bahramy +6
The quest for nonmagnetic Weyl semimetals with high tunability of phase has remained a demanding challenge. As the symmetry breaking control parameter, the ferroelectric order can…
Magnetic generation and switching of topological quantum phases in a trivial semimetal
Alex Hiro Mayo, Hidefumi Takahashi, Mohammad Saeed Bahramy +3
Topological materials have drawn increasing attention owing to their rich quantum properties, as highlighted by a large intrinsic anomalous Hall effect (AHE) in Weyl and nodal-line…
Tomographic mapping of the hidden dimension in quasi-particle interference
C. A. Marques, M. S. Bahramy, C. Trainer +7
Quasiparticle interference (QPI) imaging is well established to study the low-energy electronic structure in strongly correlated electron materials with unrivalled energy resolutio…
