N2 - Temperature variation of the magnetic susceptibility χ, resistivity ρ, specific heat C, and lattice constants has been investigated in electron-doped (formula presented) The parent (formula presented) is an antiferromagnetic band insulator, and shows an insulator-metal crossover with electron doping, together with an enhanced ferromagnetic component. We have found an enhancement of the specific heat jump (formula presented) at the spin-ordering temperature (formula presented) and interpreted the enhancement in terms of the intrinsic charge separation.
