Two-dimensional model for ferromagnetic martensites

Ferromagnetic Nanoclusters in two-dimensional He

He adsorbed on graphite is an almost ideal two dimensional (2D) fermionic system. The 2D solid, where the interaction between the nuclear spins S = 1 2 is due to multiple spin exchange, has been extensively studied as a model system for strongly interacting fermions in 2D. At high densities in the second layer, three body exchange dominates and leads to Heisenberg ferromagnetism. We report on N...

Orbital ordering in the two - dimensional ferromagnetic semi - conductor

PACS. 71.20.-b – Electron density of states and band structure of crystalline solids. PACS. 71.20.Be – Transition metals and alloys. Abstract. – We present the results of electronic structure calculations for the two-dimensional ferromagnet Rb2CrCl4. They are obtained by the augmented spherical wave method as based on density functional theory and the local density approximation. In agreement w...

Stationary Structures in Two-Dimensional Continuous Heisenberg Ferromagnetic Spin System

Stationary structures in a classical isotropic two-dimensional continuous Heisenberg ferromagnetic spin system are studied in the framework of the (2 + 1)-dimensional Landau–Lifshitz model. It is established that in the case of ~ S(~r, t) = ~ S(~r − ~vt) the Landau–Lifshitz equation is closely related to the Ablowitz–Ladik hierarchy. This relation is used to obtain soliton structures, which are...

Two-dimensional magnetic resonance tomographic microscopy using ferromagnetic probes

We introduce the concept of computerized tomographic microscopy in magnetic resonance imaging using the magnetic fields and field gradients from a ferromagnetic probe. We investigate a configuration where a two-dimensional sample is under the influence of a large static polarizing field, a small perpendicular radio-frequency field, and a magnetic field from a ferromagnetic sphere. We demonstrat...
