Single phase iron-substituted 124, (YBa2Cu4\_xFexOy) has been obtained in the range of 0 ~ x ~< 0.05 at oxygen pressure of 200 bar and 100 bar. Greater Fe substitution at elevated P(O2) destabilised the 124 and 247 phases in favor of a tetragonal 123 phase . The solubility of Fe in FeT-123 phase inc
Isothermal compressibilities, KT, at 298.15 K and ambient pressure were obtained from published sources for more than 150 liquids of various fimctionahty, either directly or via the adiabatic compressibilities, tr.s They were related to other properties of these liquids by means of a stepwise linear
