Strong ferromagnetic coupling in the K2NiF4-structured oxide La0.8Sr1.2Mn0.6Rh0.4O4

Abstract:
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 μ(B) per Mn cation; the bulk magnetisation stems from the alignment by the magnetic field of ferromagnetic (Mn/Rh)O2 sheets which are not magnetically ordered along [001] in zero applied field.
