Query: Low-Temperature Features of Nano-Particle Dynamics   In view of better characterizing possible quantum effects in the dynamics of
nanometric particles, we measure the effect on the relaxation of a slight
heating cycle. The effect of the field amplitude is studied; its magnitude is
chosen in order to induce the relaxation of large particles (~7nm), even at
very low temperatures (100mK). Below 1K, the results significantly depart from
a simple thermal dynamics scenario.
