Abstract
Raman spectra measurements of the TmPO4 crystal under external magneti c fields up to 10T are presented. At temperatures lower than 20K the m agnetic field induced structural transition theoretically predicted ea rlier is observed. The appearance of a new finite frequency Raman mode in the spectra at the critical magnetic field is the main characteris tic of the phase transition manifestation.
