Effect of polar distortions on the linear and nonlinear anomalous Hall conductivity of altermagnetic -MnTe
Mathews Benny, Sahar Izadi Vishkayi, Amar Fakhredine +2
Altermagnetic -MnTe with Néel vector along the -axis exhibits a finite anomalous Hall conductivity (AHC) and weak ferromagnetism along the -axis. As already demonstrated i…
The Fundamental Lemma of Altermagnetism: Emergence of Alterferrimagnetism
Chanchal K. Barman, Bishal Das, Alessio Filippetti +2
Recent years have seen a proliferation in investigations on Altermagnetism due to its exciting prospects both from an applications perspective and theoretical standpoint. Tradition…
Intrinsic Nonlinear Planar Thermal Hall Effect
Chanchal K. Barman
We introduce the intrinsic nonlinear planar thermal Hall effect (NPTHE)-- a dissipationless thermal response proportional to , which arises when the temperature grad…
Intrinsic Berry Curvature Driven Anomalous Hall and Nernst Effect in CoMnSn
Bishal Das, Arnab Bhattacharya, Amit Chanda +5
Magnetic topological semimetals often exhibit unusual electronic and thermal transport due to nontrivial bulk band crossings, enabling simultaneous realization of large anomalous H…
Role of Disorder in Third-order Anomalous Hall Effect in Time-reversal Symmetric Systems
Chanchal K. Barman, Arghya Chattopadhyay, Surajit Sarkar +2
The third-order anomalous Hall effect (TOAHE) driven by Berry connection polarizability in Dirac materials offers a promising avenue for exploring quantum geometric phenomena. We i…
Highly efficient field-free switching by orbital Hall torque in a MoS2-based device operating at room temperature
Antonio Bianco, Michele Ceccardi, Raimondo Cecchini +6
Charge-to-spin and spin-to-charge conversion mechanisms in high spin-orbit materials are the new frontier of memory devices. They operate via spin-orbit torque (SOT) switching of a…
