Temperature-dependent infrared refleetivity of ceramic samples of YBa~Cu4Os and substituted YBa2Cu+Os are presented. Substitutions include rare ear'& ions for Y, and part substitutions of Zn for Cu, Ca for Y and La for Ba. It is observed that the phonon near 300 cm "t softens as the temperature is l

Samples of YBazCudOs are prepared by means of a new high oxygen pressure technique employing oxygen-HIP. Both magnetization and resistivity measurements show the superconductivity transition at 82.5 K. The lower and upper critical fields of YBa&\_t40s are obtained from the magnetization measurements
