Abstract:
The helimagnetic ground state was induced in the hexagonal Y2Fe17 and Lu2Fe17 intermetallics by hydrostatic pressure above 1.05 and 0.3 GPa, respectively. The observed incommensurate helical structure was characterized by a propagation vector (0 0 tz) and by a metamagnetic transition at the critical field Hc. The new incommensurate magnetic structure has been revealed now in Lu2Fe17 at magnetic fields above Hc at low temperatures. A detailed pressure-temperature-field evolution of the magnetic structures in Y2Fe17 and Lu2Fe17 is presented.
