Antiferromagnetic behavior in S = 2 layered RbMnF 4
نویسنده
چکیده
The magnetic properties of layered-perovskite RbMnF4 have been investigated by neutron powder diffraction. This compound exhibits a magnetic ordering below T,=3.7&0.2 K. The resolution of the magnetic structure at 1.5 K indicates that RbMnF; orders as a collinear antiferromagnet. The propagation vector is k=O and the magnetic moment of each sublattice has a value of 2.97( 3) pfi The strong reduction of the observed magnetic moment. should be attributed to a particularly high two-dimensional character of this compound.

The magnetic structure and electronic ground state of the layered perovskite Ba(2)IrO(4) have been investigated using x-ray resonant magnetic scattering. Our results are compared with those for Sr(2)IrO(4), for which we provide supplementary data on its magnetic structure. We find that the dominant, long-range antiferromagnetic order is remarkably similar in the two compounds and that the elect...
متن کاملOscillatory interlayer exchange coupling and its temperature dependence in [Pt/Co]3/NiO/[Co/Pt]3 multilayers with perpendicular anisotropy.
Interlayer exchange coupling that oscillates between antiferromagnetic and ferromagnetic as a function of NiO thickness has been observed in [Pt(5 A)/Co(4 A)](3)/NiO(t(NiO) A)/[Co(4 A)/Pt(5 A)](3) multilayers with out-of-plane anisotropy. The period of oscillation corresponds to approximately 2 monolayers of NiO. This oscillatory behavior is possibly attributed to the antiferromagnetic ordering...
