Anomalous Hall and Nernst effect switching via staggered rotation in a kagome antiferromagnetic semimetal

Autor: Pradhan, Subhadip, Samanta, Kartik, Nandy, Ashis K.

The intricate interplay between magnetism and the topology of electronic structures provides a rich avenue for tailoring materials with unique and potent anomalous transport properties. In this paper, we present a strategy for inducing robust Berry c

Pressure-Driven Transitions in La2CoTiO6: Antiferromagnetic Insulator to Nonmagnetic Metal via Antiferromagnetic Metal in a Double Perovskite Oxide

Autor: Nandi, Sromona, Pradhan, Subhadip, Nandy, Ashis K., Manna, Rudra Sekhar

Publikováno v: Phys. Rev. B 110, 085101 (2024)

In double perovskite oxides (A$_2$BB$^\prime$O$_6$), magnetism often arises from diluted magnetic lattices, created by combining a perovskite structure with localized 3$d$ magnetic elements (B) alongside another perovskite lattice containing nearly n

Anomalous Hall effect induced by Berry curvature in topological nodal-line van der Waals ferromagnet Fe$_4$GeTe$_2$

Autor: Bera, Satyabrata, Chatterjee, Sudipta, Pradhan, Subhadip, Pradhan, Suman Kalyan, Kalimuddin, Sk, Bera, Arnab, Nandy, Ashis K., Mondal, Mintu

The exploration of nontrivial transport phenomena associated with the interplay between magnetic order and spin-orbit coupling (SOC), particularly in van der Waals (vdW) systems has gained a resurgence of interest due to their easy exfoliation, ideal

Observation of anisotropic Dirac cones in the topological material Ti2Te2P

Autor: Dhakal, Gyanendra, Kabir, Firoza, Nandy, Ashis K., Aperis, Alex, Sakhya, Anup Pradhan, Pradhan, Subhadip, Dimitri, Klauss, Sims, Christopher, Regmi, Sabin, Hosen, M. Mofazzel, Liu, Yangyang, Persaud, Luis, Kaczorowski, Dariusz, Oppeneer, Peter M., Neupane, Madhab

Publikováno v: Phys. Rev. B 106, 125124 (2022)

Anisotropic bulk Dirac (or Weyl) cones in three dimensional systems have recently gained intense research interest as they are examples of materials with tilted Dirac (or Weyl) cones indicatig the violation of Lorentz invariance. In contrast, the stu

Vector Chirality $\kappa$ Driven Topological Phase Transition and the Associated Anomalous Hall Conductivity Tuning in a Non-Collinear Antiferromagnet

Autor: Pradhan, Subhadip, Samanta, Kartik, Saha, Kush, Nandy, Ashis K.

Publikováno v: Commun Phys 6, 272 (2023)

Based on the first-principles electronic structure calculations and subsequent symmetry adapted effective low-energy $\textbf{k.p}$ theory, we show the switching of the vector chirality, $\kappa$, in a noncollinear antiferromagnet (AFM), Mn$_3$Sn, as

Defect Modulated Band Modification in Ion Implanted MgO Crystal: Experimental and Ab Initio Calculations

Autor: Bhakta, Sourav, Pradhan, Subhadip, Nandy, Ashis K., Sahoo, Pratap K.

Defects creation and annihilation is a fundamental concept in device fabrication. This report studies the optical bandgap modification in MgO by MeV Ni ion irradiation-induced defect states between valance and conduction band. Ion implantation on MgO
