XAS and MCD studies in Eu0.6Sr0.4MnO3.
Eu(1-x)Sr(x)MnO3 system is one of the perovskite manganites that exhibit the giant magneto resistance effect and the transition from the insulator phase to the metal. Eu(0.6)Sr(0.4)MnO3 behaves as a ferromagnetic semiconductor and has an Insulator-Metal (IM) transition induced by external magnetic field, which could be found only in this system among the perovskite manganites group. The mechanism of the transition was investigated by X-ray Magnetic Circular Dichroism (XMCD) at the Mn L2,3-edges of and the Eu M4,5-edges in Eu(0.6)Sr(0.4)MnO3.
