Abstract

We have observed dilatometrically two phase transitions in samples of

{YBa}_{2}

{Cu}_{3}

O_{7 - x}

with x∼0.1 prepared in three separate laboratories. These two transitions have been observed previously in heat-capacity measurements in

{YBa}_{2}

{Cu}_{3}

O_{6.9}

in the range from about 87 to about 95 K. Recent heat-capacity measurements on one of the samples have also exhibited two transitions that correspond to the dilatometric results.
