The complex phase behavior of HTS cuprates – relating thermodynamics to physical properties

Jeff Tallon, Principal Scientist

Robinson Research Institute

Victoria University of Wellington, New Zealand

┬áMore than a quarter of a century has passed since the discovery of high-Tc superconductors (HTS). The HTS group in Wellington, New Zealand, has been there since the beginning and is certainly the largest team in the southern hemisphere working in this field – primarily in applications.

This talk will highlight the connection between thermodynamics and various spectroscopies including ARPES, Raman, infrared and scanning tunneling spectroscopy. Most importantly, thermodynamics sheds clear light on the complex phase behavior of the cuprates – still considered open and controversial by many in the field. This complexity also spills over into practical applications of HTS but here again thermodynamics offers important insights. Finally the range of HTS products manufactured by our spin-out company ( will be reviewed, culminating in the development of compact and potentially portable MRI.
