Magnetic and electronic ordering phenomena in the [RuO] honeycomb lattice compound AgRuO
Walter Schnelle, Beluvalli E. Prasad, Claudia Felser +13
The silver ruthenium oxide AgRuO consists of honeycomb [RuO] layers, and can be considered an analogue of SrRuO with a different intercalation stage.…
Raman anomalies as signatures of pressure induced electronic topological and structural transitions in black phosphorus: Experiments and Theory
Satyendra Nath Gupta, Anjali Singh, Koushik Pal +4
We report high pressure Raman experiments of Black phosphorus up to 24 GPa. The line widths of first order Raman modes A, B and A of the orthorhombic phase show…
Metallic monoclinic phase in VO induced by electrochemical gating: in-situ Raman study
Satyendra Nath Gupta, Anand Pal, D. V. S. Muthu +2
We report in-situ Raman scattering studies of electrochemically top gated VO thin film to address metal-insulator transition (MIT) under gating. The room temperature monoclinic…
Coupled Phonons, Magnetic Excitations and Ferroelectricity in AlFeO3: Raman and First-principles Studies
Pradeep Kumar, A. Bera, D. V. S. Muthu +7
We determine the nature of coupled phonons and magnetic excitations in AlFeO3 using inelastic light scattering from 5 K to 315 K covering a spectral range from 100-2200 cm-1 and co…
An electron paramagnetic resonance study of Pr_{0.6}Ca_{0.4}MnO_{3} across the charge ordering transition
Rajeev Gupta, Janhavi P. Joshi, S. V. Bhat +2
We report the first electron paramagnetic resonance studies of single crystals and powders of Pr_{0.6}Ca_{0.4}MnO_{3} in the 300-4.2 K range, covering the charge ordering transitio…
