在高压下测量了金属间化合物Ce（In_（1-x）Sn_x）（3）的电阻和晶格常数。结果表明，压力的作用使CeIn 3（x = 0）的近藤温度T-K升高，Neel温度降低。压缩曲线显示体积随压力连续减小，没有任何间断。这一事实表明，随着压力的增加，化合价转变连续发生。利用Gruneisen参数对结果进行了简要的讨论。(C)1999年由Elsevier Science S.A.出版All rights reserved.
Electrical resistance and lattice parameters of the intermetallic compounds Ce(In1-xSnx)(3) have been measured at high pressure. It is found that the Kondo temperature T-K, which is estimated from the temperature showing the maximum in the rho(T) curve, is increased and the Neel temperature of CeIn3(x = 0) is decreased by the application of pressure. The compression curves show a continuous decrease in volume with pressure, without any discontinuity. This fact indicates that the valence transition occurs continuously with pressure. The results are discussed briefly by using Gruneisen parameters. (C) 1999 Published by Elsevier Science S.A. All rights reserved.
