LOW TEMPERATURE BEHAVIOR OF (Eu,La)1-xSrxMnO3 — •Yakov Mukovskii — Leninskii 4

Magnetic and transport properties of (Eu1-yLay)1-xSrxMnO3 poly- and single crystals were studied. Increasing as La as Sr leads to change from antiferromagnetic (AFM) to ferromagnetic (FM) ordering in the compounds. For some compositions application of an external magnetic field induces the transition into the FM state with changing temperature dependence of resistivity at low temperature from nonmetallic (dR/dT < 0) to metallic (dR/dT > 0) one. Magnetic susceptibility and magnetization data evidence on inhomogeneous magnetic structure in the material. The work was supported by the ISTC grant #1859
