      Indium oxide as a possible tunnel barrier in spintronic devices 

      Androulakis, J.; Gardelis, S.; Giapintzakis, John; Gagaoudakis, E.; Kiriakidis, G. (2005)
      We report the growth of ultra-thin indium oxide layers using the dc-magnetron sputtering method. We demonstrate that good quality tunnel barriers made of indium oxide can be routinely fabricated and employed in spintronic-related ...

      Magnetoresistance in LaNi1-xCoxO3 (0.3≤x≤0.6) 

      Androulakis, J.; Giapintzakis, John (2010)
      We report on a detailed study of the electrical resistivity and the magnetoresistance of the metallic members of the LaNi1-xCoxO3 series with 0.3≤x≤0.6. The low-temperature resistivity of the compounds with 0.3≤x≤0.5 ...
