  • Phase formation and superconductivity of fe-tube encapsulated and vacuum-annealed MgB2 
    Singh, K. P.; Awana, V. P. S.; Shahabuddin, M. D.; Husain, M.; Saxena, R. B.; Nigam, Rashmi; Ansari, M. A.; Gupta, Anurag; Narayan, Himanshu; Halder, S. K.; Kishan, H. (World Scienti fic Publishing Company, 2006)
    We report optimization of the synthesis parameters viz. heating temperature (TH), and hold time (thold) for vacuum-annealed (10􀀀5 Torr) and LN2 (liquid nitrogen) quenched MgB2 compound. These are single-phase compounds ...
  • Swift heavy ion irradiation of MgB2 thin films: a comparison between gold and silver ion irradiations 
    Narayan, Himanshu; Agrawal, H. M.; Kushwaha, R. P. S.; Kishan, H.; Bhatt, Ravindra K. (2007)
    The effect of 200 MeV Au ion irradiation on the temperature and field dependence of the critical current density, Jc, of MgB2 thin films on sapphire substrates is reported. The results have been presented in comparison ...
