Abstract
Recent discoveries of a new Haldane compound PbNi2V2O8 and the spin-vacancy -induced antiferromagnetism (Uchiyama et al., Phys. Rev. Lett, 83 (1999) 63 2) were studied in more detail by heat capacity measurements. The existence of the antiferromagnetic transition was more firmly proved by these measur ements. We also obtained temperature versus Mg-concentration phase diagram. (C) 2000 Elsevier Science B.V. All rights reserved.
