Magnetic clusters, ie, assemblies of a finite number (between two or three and several
hundred) of interacting spin centers which are magnetically decoupled from their …

Abstract In 1983, F. Duncan M. Haldane predicted a singlet ground state for isolated integer-
spin one-dimensional antiferromagnets with low single-ion anisotropy D. Since then, a lot of …

We have performed muon spin relaxation measurements of the frustrated kagomé lattice
spin system Sr Cr 8 Ga 4 O 19. Our results demonstrate the slowing down of the Cr spin …

The phase diagram of the ferromagnetic Kondo model for manganites was recently
investigated using computational techniques by Yunoki et al.[Phys. Rev. Lett. 80, 845 …

Intensive investigations have been launched worldwide on the resistive switching (RS)
phenomena in transition metal oxides due to both fascinating science and potential …

We report an inelastic-neutron-scattering experiment on single crystals of the one-
dimensional spin-one antiferromagnet Y 2 BaNi O 5. The data show that this compound is a …

Electronic structure of the system Y 2− x M x BaNiO 5 (M= C a, S r) was calculated for x= 0,
0.2, and 0.5 using the full-potential linearized augmented-plane-wave method. To describe …

Using an asymptotically exact real space renormalization procedure, we find that the
dimerized spin-1/2 chain is extremely stable against bond randomness. For weak …

We studied a multi-orbital Hubbard model at half-filling for two and three orbitals per site on
a two-site cluster via full exact diagonalization, in a wide range for the onsite repulsion U …

The zero temperature phase diagram of the ferromagnetic Kondo model in one dimension is
studied using numerical techniques, especially at large Hund coupling. A robust region of …
