MICHAEL MANGA: Recent Refereed Publications


Li, X., M. Manga, J.N. Nguyen and R. Jeanloz (1996) Temperature profile in a laser-heated diamond cell with external heating, and implications for the thermal conductivity of (Mg,Fe)SiO3 perovskite, Geophysical Research Letters, vol. 23, 3775-3778.

Applying external heating reduces temperature gradients in the laser-heated diamond cell by roughly a factor of two as the external temperature is raised by 300 K. A heat conduction model is presented which can account for most of the reduction. In addition, the temperature distribution measured in a (Mg0.86Fe0.14)SiO3 perovskite sample at 56 GPa is compatible the expected inverse temperature-dependence of thermal conductivity.
