Dislocation Scattering in Teflon at Low Temperatures. Optical and Magnetic Properties of Some Transition Metal Ions in Lithium Phosphate Glass

Dislocation Scattering in Teflon at Low Temperatures. Optical and Magnetic Properties of Some Transition Metal Ions in Lithium Phosphate Glass

The thermal conductivity of a sample of Teflon was measured in the temperature range 0.17 to 4.0K. A good fit to these data was obtained by using dislocation scattering of phonons and a Debye omega squared frequency distribution. The optical and magnetic behavior of chromium and manganese ions doped...

Zusammenfassung:The thermal conductivity of a sample of Teflon was measured in the temperature range 0.17 to 4.0K. A good fit to these data was obtained by using dislocation scattering of phonons and a Debye omega squared frequency distribution. The optical and magnetic behavior of chromium and manganese ions doped into Li3PO4 glass is studied, as well as other transition metal ions.
