    Control of L-type ferrimagnetism by the Ce/vacancy ordering in the A-site-ordered perovskite Ce1/2Cu3Ti4O12

    A-site-ordered perovskite Ce1/2Cu3Ti4O12 crystallizes in two different forms, one with
    random and the other with ordered Ce/vacancy distribution at the A site of the prototype
    AA′ 3 B 4O12 structure. Both phases form a G-type spin structure of Cu2+ spins below 24
    K, although their magnetisms are quite different. The former undergoes a typical
    antiferromagnetic transition, whereas the latter shows an L-type ferrimagnetism. The
    unusual ferrimagnetism is a direct consequence of the Ce/vacancy ordering.
