Temperature dependent magnetic, dielectric and Raman studies of partially disordered La2NiMnO6
Pradeep Kumar, S. Ghara, B. Rajeswaran +3
We report a detailed magnetic, dielectric and Raman studies on partially disordered and biphasic double perovskite La2NiMnO6. DC and AC magnetic susceptibility measurements show tw…
Raman evidence for coupling of superconducting quasi-particles with a phonon and crystal field excitation in superconductor Ce0.6Y0.4FeAsO0.8F0.2
Pradeep Kumar, D. V. S. Muthu, J. Prakash +2
We report inelastic light scattering experiments on superconductor Ce0.6Y0.4FeAsO0.8F0.2 from 4K to 300K covering the superconducting transition temperature Tc ~ 48.6K. A strong ev…
The Boson peak in supercooled water
Pradeep Kumar, K. Thor Wikfeldt, Daniel Schlesinger +2
We perform extensive molecular dynamics simulations of the TIP4P/2005 model of water to investigate the origin of the Boson peak reported in experiments on supercooled water in nan…
