Magnetic, structural and Mn K-edge X-ray absorption near-edge structure (XANES) spectroscopic studies have been made on the stoichiometric Lai 1-xEuxMnO3 (0 [less-than or equal to] x [less-than or equal to] 1) system with trivalent Mn3+. The system undergoes an A-type antiferromagnetic (AF) order with Neel temperature TN ranging from 139 K for LaMnO3 to 42 K for smaller EuMnO3, above which a two-dimensional ferromagnetic (2D-FM) short range fluctuation prevails with T2D > TN at low applied field. This is the result of anisotropic superexchange interaction for the A-type AF order with strong basal plane FM coupling of the orbital-ordered eg electrons and weak c-axis AF coupling of t2g electrons. The anomalous decrease of TN with increasing smaller Eu substitution is due to more localized t2g electrons from a stronger crystal field splitting and lattice distortion in the MnO6 octahedron. Both T2D and TN are field dependent and nearly merge at higher applied fields.
