摘要：

The structural, magnetic, and electrical properties of Y0.5Sr0.5MnO3 and Y0.4Sr0.6MnO3 have been measured. Magnetic data [e.g., the frequency dependence of ac susceptibility, the zero-field-cooled and field-cooled magnetization behavior, the M(H) behavior] indicate the spin-glass-like behavior in these oxides. The low-field magnetization data follow de Almeida-Thouless line. The resistivity data show insulating behavior in the spin-glass-like state and do not change with the application of a 4 T magnetic field. It has been explained that with decrease of <r(A)> (the rare-earth-site average ionic radius) the magnetic ordering changes from antiferromagnetic to spin-glass like.
