Abstract A magnetotrasnport and magnetization study has been performed in order to probe the changes in the magnetic states of the rare earth element Dysprosium. Primarily there are three magnetic states present in this element in different temperature regions; one changing at Neel temperature (T{sub N} ~ 180 K) via second order phase transition and another at Curie temperature (T{sub C} ~ 90 K) via first order magnetic phase transition (FOMT). These two transitions merge at the magnetic field above 1.5 T. The first derivative of resistivity indicates the possibility of spin fluctuation above first order phase transition in the spiral antiferromagnetic phase. The magnetoresistance up to 8 T reveals distinct features in the para, antiferromagnetic spiral and ferromagnetic regions.
