  • 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 ...
  • Low temperature magnetic properties of MnTe 
    D'Sa, J.B.C.E.; Priolkar, K.R.; Prabhu, R.B.; Sarode, P.R.; KamatDalal, V.N.; Vasanthacharya, N.Y. (Solid State Physics (India), Ed. by: S.L. Chaplot, P.S.R. Krishna and T. Sakuntala. Narosa Publishing House, New Delhi. 44; 2002; 453-454.)
    Electrical resistivity and magnetic susceptibility measurements of antiferromagnetic p-type semiconductor MnTe are presented in the 20K-300K range. A sharp increase in susceptibility at about 80K is observed and reported ...
  • Low temperature magnetic structure of MnSe 
    D'Sa, J.B.C.E.; Bhobe, P.A.; Priolkar, K.R.; Das, A.; Krishna, P.S.R.; Sarode, P.R.; Prabhu, R.B. (Pramana-Journal of Physics. 63(2); 2004; 227-232.)
    In this paper we report low temperature neutron diffraction studies on MnSe in order to understand the anomalous behaviour of their magnetic and transport properties. Our study indicates that at low temperatures MnSe has ...
  • Low-temperature neutron diffraction study of MnTe 
    D'Sa, J.B.C.E.; Bhobe, P.A.; Priolkar, K.R.; Das, A.; Paranjpe, S.K.; Prabhu, R.B.; Sarode, P.R. (Journal of Magnetism and Magnetic Materials. 285(41641); 2005; 267-271.)
    Investigation of transport and magnetic properties of MnTe at low temperatures showed anomalies like negative coefficient of resistance below 100 K and a sharp rise in susceptibility at around 83 K similar to a ferromagenetic ...
  • Neutron diffraction studies of MnSe 
    D'Sa, J.B.C.E.; Priolkar, K.R.; Das, A.; Prabhu, R.B.; Sarode, P.R.; Kamat-Dalal, V.N.; Paranjpe, S.K. (Solid State Physics India., 42. Proc. DAE solid state physics symposium. 2000; 569-570.)
  • Neutron diffraction study of MnTe 
    D'Sa, J.B.C.E.; Bhobe, P.A.; Priolkar, K.R.; Das, A.; Paranjpe, S.K; Prabhu, R.B.; Sarode, P.R. (Solid State Physics (India), Ed. by: S.L. Chaplot, P.S.R. Krishna and T. Sakuntala. Narosa Publishing House, New Delhi. 44; 2002; 435-436.)
    We report our neutron diffraction studies at low temperature on MnTe. The low temperature data indicates presence of another crystallographic phase along with the high temperature antiferromagnetic hexagonal phase. This ...
  • Structural and magnetic phase diagram of MnSe(1-x)Te(x) 
    Priolkar, K.R.; Bhobe, P.A.; D'Sa, J.B.C.E.; Das, A.; Krishna, P.S.R.; Sarode, P.R. (Solid State Phys. DAE Symp. 50; 2005; 833-834.)
    Neutron diffraction studies as a function of temperature on solid solutions of MnSe and MitTe in the Se rich region are presented. As Te is doped in MnSe, the structural phase transition wherein some portion of the sample ...
  • Structural and magnetic phase transitions in MnTe-MnSe solid solutions 
    Ingle, K.E.; D'Sa, J.B.C.E.; Das, A.; Priolkar, K.R. (Journal of Magnetism and Magnetic Materials. 347; 2013; 68-71.)
    Neutron diffraction studies as a function of temperature on solid solutions of MnSe and MnTe in the Se rich region are presented. Interestingly as Te is doped in MnSe, the structural transformation to NiAs phase diminishes, ...
