摘要：
The effect of high chromium concentrations on the charge and orbital ordering in manganites is studied using neutron diffraction and magnetic measurements. It is found that the Nd0.6Ca0.4Mn0.5Cr0.5O3 manganite exhibits a CE-type antiferromagnetic ordering with a weak ferromagnetic component below 160 K. In the Nd0.6Ca0.4Mn0.5Cr0.5O3 manganite, the Mn and Cr ions form antiferromagnetic zigzag chains that are likewise antiferromagnetically coupled with one another in the basal plane and are arranged along the b axis of the orthorhombic structure with oppositely directed spins. An applied magnetic field of 5 T does not change the magnetic structure.
