Nonrelativistic and Relativistic Contributions to Spin-Momentum Locking and Spin Photogalvanic Effect in an Altermagnetic Multiferroic
Giuseppe Cuono, Subhadeep Bandyopadhyay, Amar Fakhredine +6
Altermagnetic multiferroics provide a platform where non-relativistic spin-momentum locking (SML) coexists with relativistic spin textures, yet disentangling their different origin…
Revisiting the topological properties of XMg2Bi2 (X = Ca, Sr, Ba, Yb and Eu)
Antoni Facca, Xujia Gong, Amar Fakhredine +2
Density functional theory is known to underestimate band gaps in semiconductors and to over- estimate inverted band gaps, frequently exaggerating the predicted size of the topologi…
Defect Geometry Selects Polar and Anomalous Hall Phases in Two-Dimensional Altermagnets
Xujia Gong, Amar Fakhredine, Hosein Alavi-Rad +6
Point defects in altermagnets can create phases absent in the pristine host by selectively breaking crystal symmetries. Combining symmetry analysis, first-principles calculations,…
Magnetically tunable symmetry-enforced nodal lines producing huge anomalous Hall conductivity in altermagnetic -MnTe
Mathews Benny, Xujia Gong, Amar Fakhredine +17
Altermagnetic -MnTe exhibits huge anomalous Hall conductivity (AHC) up to room-temperature together with weak ferromagnetism arising from spin and orbital polarizations. We clar…
Symmetry-protected nodal planes and accidental nodal surfaces in mixed odd-even wave spin-momentum locking of relativistic altermagnets
Xujia Gong, Amar Fakhredine, Sahar Izadi Vishkayi +1
Non-relativistic spin--momentum locking in altermagnets exhibits an even number of nodal planes. In the relativistic limit, the number of nodal planes can be lowered by symmetry re…
Relativistic spin-momentum locking in ferromagnets
Xujia Gong, Amar Fakhredine, Carmine Autieri
The relativistic spin-momentum locking has been proven in time-reversal-breaking classes of materials with zero net magnetization in the non-relativistic limit, such as altermagnet…
Staggered Dzyaloshinskii-Moriya and canting angle in centrosymmetric altermagnetic and ferromagnetic phases: influence on the anomalous Hall effect and Weyl points
Mathews Benny, Xujia Gong, Kamil Jamroszczyk +5
We present a simple methodology to compute the anomalous Hall conductivity (AHC) as a function of the canting angles in ferromagnets and altermagnets, starting from a nonmagnetic H…
Magnetic Frustration Enforced Electronic Reconstruction in Ni intercalated NbSe: Suppression of Electronic Orders
Ashutosh S. Wadge, Alexander Kazakov, Xujia Gong +14
We investigate the single crystals of NiNbSe, revealing that Ni intercalation profoundly alters the physical properties of NbSe. Magnetic measurements clearly show…
Dirac edge states as signature of two-dimensional altermagnetic topological crystalline phase
Raghottam M. Sattigeri, Xujia Gong, Amar Fakhredine +2
Two-dimensional (2D) metallic altermagnets present exciting opportunities for both fundamental research and practical innovations. Their ability to enhance tunneling magnetoresista…
Tunability of the magnetic properties in Ni intercalated transition metal dichalcogenide NbSe
Xujia Gong, Amar Fakhredine, Carmine Autieri
We study the magnetic and electronic properties of Ni-intercalated NbSe.We calculate the magnetic exchanges of NiNbSe ( and ) and find that the out-of…
Pressure-induced dimerization and molecular orbitals formation in Na2RuO3 with strong correlation-enhanced spin-orbit coupling effect
Xujia Gong, Wei Wang, Wen Lei +4
First-principles calculations and simulations are conducted to clarify the nonmagnetic insulating ground state of the honeycomb lattice compound Na2RuO3 with 4d^4 electronic config…
In-gap states and strain-tuned band convergence in layered structure trivalent iridate K0.75Na0.25IrO2
Xujia Gong, Carmine Autieri, Huanfu Zhou +4
Iridium oxides (iridates) provide a good platform to study the delicate interplay between spin-orbit coupling (SOC) interactions, electron correlation effects, Hund's coupling and…
