The magnitude of PA signal excited with photon energy beyond the band gap decreases down to one-third as increasing temperature from 24℃ to 180℃, and similar decrease in magnitude of PA signal down to one-fifth has been observed as increasing chopping frequency from 4 to 50 Hz. The observed change in magnitude of PA signal at first-order phase transitions is larger than the expectation from RG theory. This curious feature might be understood by the frequency dependence of heat capacity.}, pages = {71--78}, title = {超イオン導電体α-AgI型の相転移における光音響スペクトル(II)}, volume = {26}, year = {1991}, yomi = {クリタ, ミツフミ and アカオ, フミオ and ナカガワ, キミオ and ミノムラ, シゲル} }
