Abstract
Thermal diffusivities of metallic glass ribbons have been measured at different annealing stages by the photoacoustic method using a gas-coupled microphone. In a symmetrical excitation geometry of the photoacoustic experiment, heat waves were generated by a laser beam at both sides of the foils. Values of thermal diffusivities have been compared with those of the electrical conductivity measured on the same samples.Keywords
