Abstract
We have investigated the spin dynamics of a distorted perovskite Eu06Sr04MnO3 by means of Mössbauer spectroscopy Below 70 K the exchange interaction grows gradually and below 42 K the spins turn into a cluster glass state The magnetic fieldinduced insulatortometal IM transition at low temperature is a transition from cluster glass to ferromagnet The induced metallic phase seems to be still in nonuniform electronic state On the other hand at 80 K just above T c of the induced ferromagnet a metamagnetic transition was observed
