  • Disorder induced negative magnetization in LaSrCoRuO(6) 
    Murthy, P.S.R.; Priolkar, K.R.; Bhobe, P.A.; Das, A.; Sarode, P.R.; Nigam, A.K. (Journal of Magnetism and Magnetic Materials 322(22); 2010; 3704-3709.)
    This paper reports effect of thermally induced disorder on the magnetic properties of LaSrCoRuO6 double perovskite. While the ordered sample is antiferromagnetic, the disordered sample exhibits negative values of magnetization ...
  • Induced supersolidity in a mixture of normal and hard-core bosons 
    Mishra, T.; Pai, R.V.; Das, B.P. (Physical Review B. 81(2); 2010; Article ID: 024503.)
    We present a scenario where a supersolid is induced in one of the components of a mixture of two species bosonic atoms where there are no long-range interactions. We study a system of normal and hard-core boson mixture ...
  • Correlation between local structure distortions and martensitic transformation in Ni-Mn-In alloys 
    Lobo, D.N.; Priolkar, K.R.; Bhobe, P.A.; Krishnamurthy, D.; Emura, S. (Applied Physics Letters. 96(23); 2010; Article ID: 232508.)
    The local structural distortions arising as a consequence of increasing Mn content in Ni(2)Mn(1+x)In(1-x) (x=0, 0.3, 0.4, 0.5, and 0.6) and its effect on martensitic transformation have been studied using extended x-ray ...

    Lecointre, A.; Bessiere, A.; Viana, B.; AitBenhamou, R.; Gourier, D. (Radiation Measurements. 45(41704); 2010; 273-276.)
    The series of whitlockite compounds Ca(3)(PO(4))(2) and Ca(9)Ln(PO(4))(7) (Ln = Pr, Eu, Tb, Dy, Ho, Er, Lu) was studied in radioluminescence (RL) and thermally stimulated luminescence (TSL) excited by X-rays. f-f emission ...
  • Red persistent luminescent silicate nanoparticles 
    Lecointre, A.; Bessiere, A.; Viana, B.; Gourier, D. (Radiation Measurements. 45(41704); 2010; 497-499.)
    Red persistent luminescent diopside nanoparticles doped with Mn(2+) and codoped with RE(3+) (Eu(2+), Dy(3+)) have been obtained by sol-gel method.The influence of codoping rare earth ions on the persistent luminescence was ...
