We have used the pulsed laser deposition (PLD) technique followed by post-annealing process with magnesium vapor at 700 ◦C for 30 min to grow a high-quality CrO2/MgB2 bilayer prepared on Al2O3 (1102) single crystal. The X-ray diffraction patterns...
We have discovered occurrence of strong narrow spectral lines in gold nanoparticles deposited on fluorine-doped tin oxide substrates at wavelengths 410, 440 and 550 nm under influence of 808 nm wavelength laser illumination with power about 200 mW....
We present a complex fluorescence study of a series of gadolinium oxide polycrystalline powders singly, doubly and triply doped with trivalent rare earth ions (Er3+, Tb3+, and Dy3+), to explore a possibility of their use as materials for white light...
The powder samples were sintered at 800∘C for 2 h in order to develop the stable hexagonal phase, characteristic of the SrFe12O19 structure. The consequences of Pb substitution (at iron sites) on various structural parameters like lattice constants...
In this paper, we are presenting the effects of pressure using cold isostatic press (CIP) on the physical properties of nano-SiC-doped bulk sample Mg1.15B1.96C0.04. Effects on lattice parameters, critical current density (Jc), upper critical field (...
The paper reports the JC(H, T ) of nano-ZnO doped MgB2 samples calculated from M–H loop measurements. Volume pinning forces at different temperatures have been evaluated as a function of the field from the JC–H data. Two different scaling laws, one...
The effect of the ball milling time (BMT) on the substitution of the carbon in the glucose doped MgB2 samples is investigated here. Using in situ solid state reaction, four different doped samples of Mg(B.98C.02)2 were prepared by mixing powders of...
In this paper, the critical current density measured from the real part of ac-susceptibility is in agreement with that calculated from Bean’s formula at constant frequency ( f = 98 Hz) in the temperature range 30–38K for a pure MgB2 sample. The...
We present a complex fluorescence study of a series of gadolinium oxide polycrystalline powders singly, doubly and triply doped with trivalent rare earth ions (Er3+, Tb3+, and Dy3+), to explore a possibility of their use as materials for white light...
