Hydrostatic and chemical pressure driven crossover from commensurate to the incommensurate state of the Weyl semimetal MnSn
K. Bhattacharya, A. K. Bharatwaj, C. Singh +5
The observation of large intrinsic anomalous Hall conductivity (AHC) in the non-collinear antiferromagnetic (AFM) phase of the Weyl semimetal MnSn generates enormous interest i…
Electronic and magnetic ground state of 4 double perovskite ruthenates ALaRuO (A Ca, Sr, Ba)
Asha Ann Abraham, Roumita Roy, Ruta Kulkarni +2
4 transition metal oxide (TMO) offers an intriguing puzzle for their electronic and magnetic ground state. They are in the cross-over regime of strong spin orbit interaction (SO…
Two-band conduction as a pathway to non-linear Hall effect and unsaturated negative magnetoresistance in the martensitic compound GdPd2Bi
Snehashish Chatterjee, Saurav Giri, Subham Majumdar +9
The present work aims to address the electronic and magnetic properties of the intermetallic compound GdPdBi through a comprehensive study of the structural, magnetic, electric…
Structure, magnetism and electronic properties in 3-5 based double perovskite (SrCa)FeIrO (0 1): A combined experimental and theoretical investigation
K. C. Kharkwal, Roumita Roy, Harish Kumar +6
The 3-5 based double perovskites offer an ideal playground to study the interplay between electron correlation () and spin-orbit coupling (SOC) effect, showing exotic phys…
Pronounced 2/3 magnetization plateau in a frustrated = 1 isolated spin-triangle compound: Interplay between Heisenberg and biquadratic exchange interactions
S. Chattopadhyay, B. Lenz, S. Kanungo +13
We report the synthesis and characterization of a new quantum magnet [2-[Bis(2-hydroxybenzyl)aminomethyl]pyridine]Ni(II)-trimer (BHAP-Ni3) in single-crystalline form. Our combined…
Active role of the nonmagnetic cations in magnetic interactions for the double-perovskite Sr2BOsO6 (B=Y, In, Sc)
Sudipta Kanungo, Binghai Yan, Claudia Felser +1
Using first-principles density functional theory, we have investigated the electronic and magnetic properties of recently synthesized and characterized 5d double-perovskites Sr2BOs…
Na4IrO4: Square-Planar Coordination of a Transition Metal in d5 Configuration due to Weak On-Site Coulomb Interactions
Sudipta Kanungo, Binghai Yan, Patrick Merz +2
Local environments and valence electron counts primarily determine the electronic states and physical properties of transition metal complexes. For example, square-planar surroundi…
Mechanism of Ferroelectricity in Perovskites - a Model Study
Paolo Barone, Sudipta Kanungo, Silvia Picozzi +1
By means of a model Hamiltonian approach we study the role of volume expansion, Hund's coupling and electron correlation in the standard hybridization mechanism for ferroelectricit…
