We present a new method for measuring attenuation in single crystals of minerals and in reference materials over a frequency range of 1-1e-4 Hz via nanoindentation. In the experiments, we calculate the phase lag between a sinusoidal load applied to the tip of the nanoindenter and its displacement into and out of the tested sample, which provides a measure of the inverse quality factor 1/Q (i.e., attenuation) of the sample.
