Transitions between different types of spin ordering in holmium films have been studied in the temperature range 10-140 K and magnetic fields 0-4 T. The magnetic phase diagram in H-T coordinates indicates the presence of transitions between intermediate helicoid phases from the helix state to such spin structures, such as ferromagnet (ferro), fan (fan) and sliding structures (spin-slip). Arrott's method made it possible to determine the critical indices for each of the transitions. Based on the critical indices, a selection of models and their combinations applicable to describe the mentioned non-collinear spin states was made. Keywords: holmium films, spin structures, spin-reorientation transition, critical indices.
