    UmaSubramanian; Naik, S.J.; Tangsali, R.B.; Salker, A.V. (Proc. Int. Conf. on Nanoscience and Nanotechnology (ICONN 2010). SRM Univ., Chennai. 24-26 Feb 2010. 2010; 115-116)
    In this work nano range C0WO(4) powder samples doped with different concentrations of Ce3+ ions were prepared by coprecipitation method. The samples were also sintered at various temperatures and characterized using ...
  • Density-matrix renormalization group studies of mixture of two different ultracold bosonic atoms 
    Mishra, T.; Pai, R.V.; Das, B.P. (Journal of Physics: Conference Series. 80; 2007; Article ID 012039)
    We investigate the ground state phase diagram for a two species Bose mixture in a one dimensional optical lattice using the finite size density matrix renormalization group (FSDMRG) method. We present our result for different ...
  • Magnetic, Transport and Spectroscopic Properties of PrBaCo(2)O(5.35) 
    Ganorkar, S.; Priolkar, K.R.; Sarode, P.R.; Banerjee, A.; Sathe, V.G. (AIP Conference Proceedings. 1349; 2011; 1129-1130)
    Oxygen deficient double perovskites PrBaCo(2)O(5.35) has been studied by XRD, magnetization, resistivity, infra?red (IR) and Raman spectroscopy. Spectroscopic properties reveal that the local structure around Co ions plays ...

    Mund, H.S.; Dashora, A.; Sahariya, J.; Bhamu, K.C.; Priolkar, K.R.; Lobo, N.; Itou, M.; Sakurai, Y.; Ahuja, B.L. (AIP Conference Proceedings. 1349; 2011; 1123-1124.)
    The spin dependent momentum densities in Ni(2)MnSn Heusler alloy have been measured at 10 and 300 K using magnetic Compton scattering. For these measurements, we have used 182.79 keV circularly polarized synchrotron radiation ...
  • Comparison of EXAFS foil spectra from around the world 
    Kelly, S.D.; Bare, S.R.; Greenlay, N.; Azevedo, G.; Balasubramanian, M.; Barton, D.; Chattopadhyay, S.; Fakra, S.; Johannessen, B.; Newville, M.; Pena, J.; Pokrovski, G.S.; Proux, O.; Priolkar, K.R.; Ravel, B.; Webb, S.M. (Journal of Physics: Conference Series. 190(1); 2009; Article ID: 012032)
    The EXAFS spectra of Cu and Pd foil from many different beamlines and synchrotrons are compared to address the dependence of the amplitude reduction factor (S02) on beamline specific parameters. Even though S02 is the same ...
  • Effect of rare earth size on structural, magnetic and transport properties of RBaCo(2)O(5.5) 
    Ganorkar, S.; Priolkar, K.R.; Sarode, P.R.; Banerjee, A. (AIP Conference Proceedings. 1447; 2012; 1141-1142.)
    Oxygen deficient double perovskites RBaCo(2)O(5.5) (R=Pr, Nd, Sm, Gd and Y) has been studied by XRD, magnetization and resistivity measurements. It has been found that the as rare earth size decreases, the distortions in ...
  • Hybridization effects in Ni-Mn based shape memory alloys: XAFS study 
    Priolkar, K.R.; Bhobe, P.A.; Sarode, P.R. (Advanced Materials Research. 52; 2008; 155-164)
    Martensitic and magnetic properties of ferromagnetic shape memory alloys are known to depend up on structural modulations and associated changes in the Fermi surface. These modulations although periodic and spanning over ...
