Non thermal isostructural electrically driven insulator-metal transition and electro-strain in layered cobaltate
Abdul Ahad, R. Rawat, F. Rahman +1
We report here a discovery of electrically driven insulator to metal transition (IMT) and concomitant isostructural volume expansion in the layered cobaltates which otherwise do no…
Magnetic and orbital correlations in multiferroic CaMnO probed by x-ray resonant elastic scattering
K. Gautam, S. S. Majid, S. Francoual +6
The quadruple perovskite CaMnO is a topical multiferroic, in which the hierarchy of electronic correlations driving structural distortions, modulated magnetism, and orbi…
Role of the V-V dimerization in insulator-metal transition and optical transmittance of pure and doped VO2 thin films
S. S. Majid, S. R. Sahu, A. Ahad +7
Insulator to metal (IMT) transition (T 341 K) in the VO2 accompanies transition from an infrared (IR) transparent to IR opaque phase. Tailoring of the IMT and associated…
Mott-Hubbard insulator-metal transition in the VO2 thin film: A combined XAS and resonant PES study
S. S. Majid, K. Gautam, A. Ahad +4
We have analyzed spectral weight changes in the conduction and the valence band across insulator to metal transition (IMT) in the VO2 thin film using X-ray absorption spectroscopy…
A setup for Seebeck coefficient measurement through controlled heat pulses
Abdul Ahad, D. K. Shukla
A setup is designed for measuring the Seebeck coefficient (S) of materials in form of thin film, bar and wire. The main feature of this setup is control in heating and cooling cycl…
