Abstract
The Debye temperatures thea of alumina- and titania-supported iron par ticles were determined using Mossbauer spectroscopy between 5 and 280 K. The Debye temperatures were obtained from a nonlinear optimization algorithm using the temperature dependence of the second order Doppler shift (SOD) and the resonant absorption area (RAA). To test its relia bility, the same method was used to determine theta of an alpha-iron-f oil and pyrophoric iron.
