      Effect of vacancy doping on the Haldane spin-liquid state in PbNi2-xMgxV2O8 

      Zorko, A.; Arčon, D.; Lappas, A.; Giapintzakis, John; Saylor, C.; Brunel, L. C. (2002)
      The effect of spin-vacancy doping on the ground state of the quasi-one-dimensional S=1 quantum antiferromagnet PbNi2V2O8 is studied by X band as well as high-field ESR. A very broad ESR line is observed at low temperatures ...

      Near critical behavior in the two-dimensional spin-gap system SrCu2(BO3)2 

      Zorko, A.; Arčon, D.; Lappas, A.; Giapintzakis, John (2002)
      The temperature dependence of the powdered X-band ESR spectra has been measured in a two-dimensional spin-gap system SrCu2(BO3)2 in the temperature range between 5 and 300 K. The spectra are composed of two overlapping ...
