The resistivity along the c-axis of a single crystal abruptly decreases with increasing pressure up to 0.9 GPa at room temperature. The pressure-induced insulator-to-metal-to-insulator(IMI) transitions in the complex have been found at around 0.8 and 0.9 GPa, respectively. The absorption spectra were measured with a diamond-anvil cell up to 3 GPa at room temperature. The absorption spectra of Pt(bqd)2 markedly change at around the pressures which show the IMI transitions. The pressure-induced IMI transitions and the resistivity minimum arise from the change of the electronic states of Pt(bqd)2 at high pressures., 投稿論文}, pages = {55--59}, title = {高圧下における一次元白金錯体の絶縁体-金属-絶縁体転移と電子スペクトル}, volume = {50}, year = {2000}, yomi = {タケダ, ケイキ and シロタニ, イチミン and ヤクシ, キュウヤ} }
