Research Interests

Carl Stager received his undergraduate education at McMaster University and his graduate education at the Massachusetts Institute of Technology. He received a Ph.D. degree in 1961. This was followed by a research position at the Frances Bitter Magnet Laboratory at MIT. In 1963 he joined the Physics Department at McMaster.

Dr. Stager's research is focused on the magnetic properties of matter. The main experimental technique employed is measurement of the bulk magnetic properties. A versatile SQUID (Superconducting Quantum Interference Device) magnetometer, with a high field superconducting magnet, is used to carry out magnetization measurements over extended ranges of temperature and applied magnetic field.

Current work is centred on the study of geometrically frustrated magnetic materials. The fundamental interaction between the individual magnetic moments predicts an arrangement of the magnetic moments that is incompatible with the geometrical structure of the material, which is dictated by the chemical interactions. Other projects include studies of high temperature superconductors and the development of improved experimental and data analysis techniques connected with the measurement of bulk magnetic properties.
