摘要：

Substitution of diamagnetic Rh-III into the antiferromagnet LaSrMnO4 produces the first example of a K2NiF4 (n=1 Ruddlesden-Popper) oxide with strong ferromagnetic interactions-in 50 kG at 5 K the magnetisation of La0.8Sr1.2Mn0.6Rh0.4O4 is close to saturation at 2.50 mu(B) per Mn cation; the bulk magnetisation stems from the alignment by the magnetic field of ferromagnetic (Mn/Rh)O-2 sheets which are not magnetically ordered along [001] in zero applied field.
