      Brownian-like kinematics of ball milling for particulate structural modeling 

      Doumanidis, C. C.; Kaabi, H. A. Al; Alzaabi, A. S. M.; Gunduz, I. E.; Rebholz, Claus; Doumanidis, C. C. (2016)
      Ball milling motion has been previously studied through computationally expensive, off-line experimental video processing and numerical simulations by the discrete element method. This research establishes a more efficient ...

      Ferromagnetic and antiferromagnetic interactions in lanthanum cobalt oxide at low temperatures 

      Androulakis, J.; Katsarakis, N.; Giapintzakis, John (2001)
      Systematic dc and ac magnetic susceptibility studies have been performed on single-phase (formula presented) powder samples. Evidence is presented in support of the existence of ferromagnetic (FM1, FM2) and antiferromagnetic ...

      Impurity-induced antiferromagnetic order in the Haldane-gap compound PbNi2-xMgxV2O8 (x=0.24) 

      Lappas, A.; Alexandrakis, V.; Giapintzakis, John; Pomjakushin, V.; Prassides, K.; Schenck, A. (2002)
      An investigation of the effect of nonmagnetic Mg doping in the Haldane gap system PbNi2V2O8 is presented. Specifically, the magnetic properties of the quasi-one-dimensional compound PbNi2-xMgxV2O8 (x =0.24), located in the ...

      LaSrMnCoO6: A new cubic double perovskite oxide 

      Androulakis, J.; Katsarakis, N.; Giapintzakis, John; Vouroutzis, N.; Pavlidou, E.; Chrissafis, K.; Polychroniadis, E. K.; Perdikatsis, V. (2003)
      Single-phase polycrystalline powder samples of the double perovskite oxide LaSrMnCoO6 were synthesized by the Pechini (citrate-gel) technique. The structural, magnetic and electrical properties of the obtained powders were ...
