Nature of field-induced transitions and hysteretic magnetoresistance in non-collinear antiferromagnet EuIn2As2
Karan Singh, Jan Skolimowski, Giuseppe Cuono +8
We examine the magnetic and electrical transport properties of the hexagonal EuIn2As2 compound, combining experimental and theoretical results. This compound is predicted to be an…
Persistent spin textures, altermagnetism and charge-to-spin conversion in metallic chiral crystals TMX
Karma Tenzin, Berkay Kilic, Raghottam Sattigeri +6
Chiral crystals, due to the lack of inversion and mirror symmetries, exhibit unique spin responses to external fields, enabling physical effects rarely observed in high-symmetry sy…
Dirac edge states as signature of two-dimensional altermagnetic topological crystalline phase

Two-dimensional (2D) metallic altermagnets present exciting opportunities for both fundamental research and practical innovations. Their ability to enhance tunneling magnetoresista…
Staggered Dzyaloshinskii-Moriya inducing weak ferromagnetism in centrosymmetric altermagnets and weak ferrimagnetism in noncentrosymmetric altermagnets
Carmine Autieri, Raghottam M Sattigeri, Giuseppe Cuono +1
The Dzyaloshinskii-Moriya interaction (DMI) has explained successfully the weak ferromagnetism in {\it some} centrosymmetric antiferromagnets. However, in the last years, it was ge…
