Electron vs. hole doping in infinite-layer nickelates: electronic structure, magnetism and correlations
Ezra Day-Roberts, Fabio Bernardini, Harrison LaBollita +3
The observation of superconductivity in undoped infinite-layer nickelates NiO ( = rare earth) challenges our current understanding and calls for a re-examination of the u…
Infinite-layer fluoro-nickelates as model materials
F. Bernardini, V. Olevano, X. Blase +1
We study theoretically the fluoro-nickelate series NiF ( Li, Na, K, Rb, Cs) in the tetragonal infinite-layer structure. We use density functional theory to dete…
Magnetic competition in iron-based germanide and silicide superconductors
P. Villar Arribi, F. Bernardini, L. de'Medici +3
We address the ferromagnetic tendencies detrimental for superconductivity that are related to the substitution of the pnictogen As atom with Ge or Si, together with additional subs…
Pressure-induced insulator-metal transition in EuMnO3
R. Qiu, E. Bousquet, A. Cano
We study the influence of external pressure on the electronic and magnetic structure of EuMnO3 from first-principles calculations. We find a pressure-induced insulator-metal transi…
Iron-based superconductivity extended to the novel silicide LaFeSiH
F. Bernardini, G. Garbarino, A. Sulpice +6
We report the synthesis and characterization of the novel silicide LaFeSiH displaying superconductivity with onset at 11 K. We find that this pnictogen-free compound is isostructur…
Effect of uniaxial pressure on the magneto-structural transitions of iron arsenide superconductors
A. Cano, I. Paul
We study theoretically the variation of the magnetic and the structural transition temperatures of the iron arsenide superconductors with external uniaxial stress. We show that the…
High impact of spin-nematic order on the lattice domains in thin films of iron-based superconductors
A. Cano
The spin-nematic scenario proposed for the structural instability of iron-based superconductors is studied theoretically within a Ginzburg-Landau approach in epitaxial thin films.…
Magnetoelastic Effects in Iron Telluride
I. Paul, A. Cano, K. Sengupta
Iron telluride doped lightly with selenium is known to undergo a first order magneto-structural transition before turning superconducting at higher doping. We study the effects of…
Interplay of magnetic and structural transitions in Fe-based pnictide superconductors
A. Cano, M. Civelli, I. Eremin +1
The interplay between the structural and magnetic phase transitions occurring in the Fe-based pnictide superconductors is studied within a Ginzburg-Landau approach. We show that th…
Aharonov-Bohm oscillations in the local density of states
A. Cano, I. Paul
The scattering of electrons with inhomogeneities produces modulations in the local density of states of a metal. We show that electron interference contributions to these modulatio…
Electromagnon Resonances in the Optical Response of Spiral Magnets
A. Cano
The optical response of spiral magnets is studied, with special attention to its electromagnon features. We show that these features trace back to the resonant magnetoelectric resp…
