High precision electrical resistance measurements of pure dysprosium were performed in the temperature range from 4.2 K to 300 K on cooling and warming. We have observed the electrical resistance temperature hysteresis at the order-order transition due to existence of the mixed spiral - ferromagnetic phase and that at order-disorder transition, caused by a new intermediate “vortex” magnetic structure.
