Abstract
The onset of the diamagnetic phase transition in aluminum is shown by analyzing the temperature dependence of the helicon resonance frequency and damping and by comparing between the theory and the experiment. Softening of the helicon mode due to the domain appearance is calculated. The critical growth of the helicon damping is connected with the phase transition nature of the domain occurrence, i.e. with the critical dynamics of diamagnetic phase transitions related to critical slowing down of the electron relaxation time.
