“…With the aid of this strategy, we can increase T c by enhancing intermolecular ferromagnetic interactions and the value of the effective spins within a molecule as well. Early studies of the noncollinear magnetic arrangements were pioneered in the coherent potential approximation [13,14] and in models of spin spirals [15,16], where the magnetic moments were treated as a vector observable. These approaches were motivated primarily by a desire to develop a finite-temperature model of magnetism, as mentioned above.…”

“…At smaller angles our calculations yield a higher stability of the magnetic moment value. At higher angles the magnetic moment decrease to l.lSpB, in contrast to zero according to [8]. With due account for the use of the cluster method of spectrum calculation in terms of a simple tight binding model by the authors of IS], we consider that the agreement is reasonable.…”

A previously proposed symmetrized method for the calculation of the electronic structure of spiral magnetic configurations is employed in the study of non-collinear magnetic configurations of iron and nickel. It is shown that there is a marked difference of the tendencies of changes in the electronic structure of both metals being studied due to the increase of the angle between the spins of neighbouring atoms. A qualitative interpretation of the observed changes is given in terms of a simple two-band model. It is also shown that the difference in the behaviour of the electronic structure of both, iron and nickel leads to a substantially different behaviour of a selfconsistent local magnetic moment and total electronic energy as a function of the angle between the spins of the neighbouring atoms.

“…The non-collinear spin structure was treated according to the scheme reported by Heine et al [27,28]. The Hamiltonian, H RL,R' L' , is defined along the global z axis, whereas the spin for each atom is arranged along the local ξ R axis.…”

The magnetic properties of amorphous Fe were investigated by examining the electronic structures of structurally disordered Fe systems generated from crystalline bcc and fcc Fe using a Monte-Carlo simulation. As a rst principles band method, the real space spin-polarized tight-binding linearized-mun-tin-orbital recursion method was used in the local spin density approximation. Compared to the crystalline system, the electronic structures of the disordered systems were characterized by a broadened band width, smoothened local density of states, and reduced local magnetic moment. The magnetic structures depend on the short range configurations. The antiferromagnetic structure is the most stable for a bcc-based disordered system, whereas the noncollinear spin spiral structure is more stable for a fcc-based system.
