The Effect of Spin-Phonon Interactions on the Thermal Conductivity of Chromium Doped MgO
Recent measurements at low temperatures on dielectrics and semiconductors containing paramagnetic ions have shown that the thermal conductivity in zero field can be very much less than that expected assuming only mass-defect scattering.1–4 The conductivity has also been shown to be field-dependent5,7–11 and to decrease to a minimum value as the spins become tuned to the dominant phonon frequency.5,6,9,10
