Direct Evidence for Multiferroic Magnetoelectric Coupling in 0.9BiFeO3-0.1BaTiO3 (2008)

Singh, Anar, Pandey, Vibhav, Kotnala, R. K., Pandey, Dhananjai

Magnetic, dielectric and calorimetric studies on 0.9BiFeO3-0.1BaTiO3 indicate strong magnetoelectric coupling. XRD studies reveal a very remarkable change in the rhombohedral distortion angle and a...

One-step atmospheric pressure synthesis of the ground state of Fe based LaFeAsO1-d superconductor (2008)

Awana, V. P. S., Vajpayee, Arpita, Mudgel, Monika, Kumar, Anuj, Meena, R. S., Tripathi, Rahul, ...

We report an easy and versatile one-step route of synthesis for newly discovered Fe based superconductor LaFeAsO1-d with d = 0.0 to 0.15. Instead of widely used high-pressure-high-temperature (HPHT)...

Inter comparison of the magneto transport of La2/3Ca1/3MnO3: Ag/In polycrystalline composites (2007)

Tripathi, Rahul, Awana, V. P. S., Balamurugan, S., Kotnala, R. K., Kishan, H., ...

In this article, we report the synthesis, magneto transport features, and magnetization of polycrystalline La2/3Ca1/3MnO3:Agx/Inx composites with x = 0, 0.1, 0.2, 0.3 and 0.4. In case of Ag the...

Magnetic properties of iron nanoparticles prepared by exploding wire technique (2006)

Alqudami, Abdullah, Annapoorni, S., Lamba, Subhalakshmi, Kothari, P C, Kotnala, R K

Nanoparticles of iron were prepared in distilled water using very thin iron wires and sheets, by the electro-exploding wire technique. Transmission electron microscopy reveals the size of the...
