      Coexistence of ferromagnetic and glassy behavior in semiconducting LaNi 0.2Co 0.8O 3 

      Androulakis, J.; Katsarakis, N.; Giapintzakis, John (2002)
      Systematic dc and ac magnetic susceptibility studies have been performed on single-phase LaNi 0.2Co 0.8O 3 powder samples. Evidence of hysteresis loops supports the existence of ferromagnetic correlations that lead to a ...

      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 ...
