Anisotropic magnetic and transport properties have been investigated for single crystals of (Nd1-zLaz)Sr2Mn2O7. We have derived the magnetic phase diagram against the La concentration z and have found that the low-temperature state is of layered antiferromagnetic with alternating MnO2-sheets. The reentrant-type charge-ordered state is observed in the limited z-region around z = 1.0 due to the released Jahn-Teller distortion. We further investigated magnetotransport properties for these antiferromagnetic manganites, and have found a large negative magnetoresistance, e.g., ρc(H)/ρc(0) ∼ 0.86 and ρab(H)/ρab(0) ∼ 0.88 at μ0H = 1 T.
