Pressure Effect of an S=1 Haldane Compound NDMAZ : Condensed Matter: Electronic Properties, etc.

概要

• 論文の詳細を見る

• We measured the heat capacity of an S = 1 Haldane compound NDMAZ under the pressure to investigate the three-dimensional magnetic ordering due to the anisotropy (D) and/or the interchain interaction. However, the experimental result shows that the Haldane gap (Δ) has been enhanced by the pressure and the magnetic ordering has not been observed. The remarkable increase of intrachain interaction (J) by the pressure will lead to the enhancement of Δ. We also discuss about the pressure-induced changes of Δ/|J| and D/|J| in this Haldane compound.
