RKKY interactions and magnetic structure of rare-earth quasicrystals

Magnetic Phases of Rare Earth Hexagonal Manganites

We describe the magnetic phases of hexagonal rare earth manganites RMnO3 using Landau theory. A minimal model based on four one-dimensional magnetic order parameters is developed.

Quadrupole Interactions in Rare-earth Intermetallic Compounds

A survey of the role played by the one-ion magnetoelastic and two-ion quadrupolar interactions on the magnetic and elastic properties of the rare-earth intermetallic compounds is given. These couplings are present in numerous systems and manifest themselves through a great variety of effects. The study of the multipolar interactions concerning the 4f shell has known a great development about ra...

Magnetic Properties of Quasicrystals

The aperiodic T-A180Mn20 phase is magnetic with an effective moment 1.3 pg / Mn. Below 4.1 K a spin glass state is observed. The T-phase and the quasi-crystalline A173Mn21Si6 phase have similar magnetic properties. The crystalline phase, obtained by annealing the T-phase, is less magnetic than the T-phase. Quasi-crystalline (qc) phases, first discovered in Al-Mn based alloys, are aperiodic crys...
