    Electrical resistivity measurements on compounds belonging to CeSi(2-x)Ga(x) (0.7 less than or equal to x less than or equal to 1.3) have been performed. The samples in this concentration range show a smooth crossover from ...
  • Resistivity and thermopower of the antiferromagnetic system MnTexSe1-x 
    Prabhu, R.B.; Kamat-Dalal, V.N.; Desa, J.B.C.E.; Bhatia, S.N. (Solid State Communications. 104(9); 1997; 565-567.)
    Measurement of resistivity and thermopower on the antiferromagnetic system MnTexSe1-x are reported for various values of x. Magnon drag contribution to the thermopower was also detected and measured in all the cases. ...
  • Structural and magnetic behaviour of CeSi(0.6)Ga(1.4) 
    Priolkar, K.R.; Pattalwar, S.M.; Mishra, P.K.; Raj, P.; Sathyamoorthy, A.; Dhar, S.K.; Sahni, V.C.; Sarode, P.R.; Prabhu, R.B. (Solid State Communications. 104(2); 1997; 71-73.)
    Crystal structure, resistivity, specific heat and magnetic susceptibility of CeSi(0.6)Ga(1.4) have been studied. The compound crystallizes in AlB2 type structure. The magnetic ordering temperature is reduced further from ...
  • Magnetic spectral response of cerium based Kondo systems 
    Priolkar, K.R.; Prabhu, R.B.; Sarode, P.R.; Rao, M.N.; Paranjpe, S.K.; Raj, P.; Sathyamoorthy, A. (Solid State Communications. 101(11); 1997; 825-829.)
    Inelastic neutron scattering studies on two cerium Kondo systems, CeSiGa and CeSn(2)In are reported. In CeSiGa the thermal evolution of the quasielastic line width indicates a strong competition between Kondo and RKKY ...
  • Effect of Te doping in MnSe: A resistivity study 
    D'Sa, J.B.C.E.; Priolkar, K.R.; Sarode, P.R.; Prabhu, R.B. (Solid State Physics (India), Ed. by: S.L. Chaplot, P.S.R. Krishna and T. Sakuntala. Narosa Publishing House, New Delhi. 44; 2002; 491-492.)
    We report our electrical resistivity measurements on NaCl type MnSe(1-y)Te(y) y=(0, 0.3, 0.4, 0.5) as a function of temperature. Alt the samples show activation type behaviour and energy gap decreasing with increasing Te ...
  • T-C degradation in cuprate superconductors from the resistivity of Yba2(Cu(1-X)M(X))(4)O(8) for M=Fe and Ni 
    Lal, R.; Awana, V.P.S.; Pandey, S.P.; Yadav, V.S.; Varandani, D.; Narlikar, A.V.; Chhikara, A.; Gmelin, E. (Physical Review B. 51(1); 1995; 539-546.)
    Systematic measurements of the resistivity of the polycrystalline samples of the YBa(2)(Cu(1−x)M(x))(4)O(8) system with M=Fe, Ni are reported. The resistivity behavior depends strongly on the dopant concentration. For the ...
  • X-ray absorption study of cerium intermetallics 
    Sarode, P.R.; Priolkar, K.R.; Prabhu, R.B. (Proc. DAE Solid State Physics Symposium, B.A.R.C., Bombay, 27-31 Dec 1993. 1993; 116.)
  • Effects of chemical-combination on x-ray k-alpha emission-spectra of chromium 
    Sarode, P.R. (X-Ray Spectrometry. 22(3); 1993; 138-144.)
    Asymmetry indices, chemical shifts and full widths at half maximum intensity (FWHM) of the chromium K-alpha sub(1) and K-alpha sub(2) x-ray emission lines were studied in chromium metal, some of its divalent, trivalent, ...
