SoftÕhard exchange-coupled layered structures with modulated exchange coupling

Magnetically soft/hard exchange-coupled Ni80Fe20 /Si3N4 /Sm40Fe60 and Ni80Fe20 /mixture/ Sm40Fe60 layered structures with induced in-plane uniaxial anisotropy were deposited by sputtering on Si ~100! substrates. The interfacial exchange coupling strength between the soft and hard layers was tailored by inserting a thin nonmagnetic insulating Si3N4 layer or by varying interfacial mixture of NiFe...

Absorption in periodic layered structures

Photonic band structure of metal-dielectric and semiconductor-dielectric layered structures are studied in the presence of a strong absorption. It is shown that absorption can enlarge some gaps by as much as 50%. # 2001 Elsevier Science B.V. All rights reserved.

Structural transition and unusually strong antiferromagnetic superexchange coupling in perovskite KAgF3.

High-purity samples of potassium trifluoroargentate(II), KAgF3, have been obtained via a novel synthetic pathway. This compound is found to exhibit an order-disorder phase transition around 230 K. Susceptibility measurements indicate that KAgF3 exhibits strong antiferromagnetic (AFM) coupling reminiscent of that found in copper(II) oxides.

Spin-Lattice Coupling in [Ni(HF2)(pyrazine)2]SbF6 Involving the HF2- Superexchange Pathway.

Magnetoelastic coupling in the quantum magnet [Ni(HF2)(pyrazine)2]SbF6 has been investigated via vibrational spectroscopy using temperature, magnetic field, and pressure as tuning parameters. While pyrazine is known to be a malleable magnetic superexchange ligand, we find that HF2- is surprisingly sensitive to external stimuli and is actively involved in both the magnetic quantum phase transiti...

Superexchange coupling and spin susceptibility spectral weight in undoped monolayer cuprates

A systematic inelastic neutron scattering study of the superexchange interaction in three different undoped monolayer cuprates (La2CuO4, Nd2CuO4 and Pr2CuO4) has been performed using conventional triple axis technique. We deduce the in-plane antiferromagnetic (AF) superexchange coupling J which actually presents no simple relation versus crystallographic parameters. The absolute spectral weight...
