In situ study of the formation and decomposition processes, under high pressure, of an infinite-layer cuprate: Ca0.5Sr0.5CuO2
The formation and decomposition of the Ca0.5Sr0.5CuO2 high pressure phase with the so-called infinite-layer structure have been followed in-situ by energy dispersive XRD using a synchrotron radiation source. The decomposition reaction of the infinite-layer phase is produced at 1200 C to yield a mixt...

| Summary: | The formation and decomposition of the Ca0.5Sr0.5CuO2 high pressure phase with the so-called infinite-layer structure have been followed in-situ by energy dispersive XRD using a synchrotron radiation source. The decomposition reaction of the infinite-layer phase is produced at 1200 C to yield a mixture of phases including the n=2 member of the Srn-1CunO2n-1 family and (Ca, Sr)2CuO3. This reaction implies a volume reduction, and the most significant changes are observed in the a-b plane, implying that the CuO2 planes are partially condensed. 4 refs. |
