| dc.description | Considerable evidence indicates that in Fe above the Curie temperature the electron system forms local magnetic moments which are relatively stable in magnitude and rotate to destroy long-range order. The local moments arise from exchange polarisation of the electron gas in a similar way to the conventional picture of the ferromagnetic ground state of the metal. The authors set up a one-electron-like Hartree-Fock-like model with a Stoner-like intra-atomic exchange interaction for calculating the electronic structure of such a system with arbitrary directions for the atomic moments. The directions for a cluster of 500-1000 atoms are assumed and fed into the calculation, from which the magnitudes of the moments are computed self-consistently using Haydock's recursion method (1980). The total energies are also obtainable. Results are presented for two simple types of magnetic configuration: spin spirals represent a smooth variation of the direction of magnetisation whereas alternating tilts form a rough variation back and forth from atom to atom. |
