      La0.95Sr0.05Coo3: An efficient room-temperature thermoelectric oxide 

      Andrbulakis, J.; Migiakis, P.; Giapintzakis, John (2004)
      Electric resistivity, thermal conductivity, and the thermopower of polycrystalline Sr-doped LaCoO3 with composition La 0.9Sr0.5CoO3 were measured. The crystal structure of the synthesized powders was determined by x-ray ...

      Recent advances in spintronics. Half-metal ferromagnets: Their role in spintronics 

      Gardelis, S.; Androulakis, J.; Migiakis, P.; Giapintzakis, John (2004)
      A review of recent advances in spintronics is presented. We report the structural, magnetic, electrical and thermal properties of the ferromagnetic half-Heusler alloy NiMnSb grown by arcmelting. The bulk material is used ...

      Synthesis and physical properties of arc melted NiMnSb 

      Gardelis, S.; Androulakis, J.; Migiakis, P.; Giapintzakis, John; Clowes, S. K.; Bugoslavsky, Y.; Branford, W. R.; Miyoshi, Y.; Cohen, L. F. (2004)
      The synthesis and physical properties of arc melted NiMnSb were studied using X-ray diffraction analysis. It was observed that the half metallicity in NiMnSb is supported by the integer saturation magnetization value at 5 ...

      Thermoelectric properties of LaNi1-xCoxO3 solid solution 

      Migiakis, P.; Androulakis, J.; Giapintzakis, John (2003)
      The thermoelectric properties of the selected members of the LaNi 1-xCoxO3 solid solution were investigated. The electrical properties of the solution investigated were determined from the doping level. The substitution ...
