Spin-wave theory of exchange-induced anisotropy
It is shown that exchange interactions of spins across the boundary between ferromagnetic and antiferromagnetic layers can cause a shift in the observed hysteresis loop of the ferromagnetic layer. The effect may be interpreted as a self-energy shift of each ferromagnetic spin due to emission and reabsorption of virtual antiferromagnetic spin waves. Emission of these waves by one ferromagnetic s...
متن کاملDiscrete breathers in classical ferromagnetic lattices with easy-plane anisotropy.
Discrete breathers (nonlinear localized modes) have been shown to exist in various nonlinear Hamiltonian lattice systems. This paper is devoted to the investigation of a classical d-dimensional ferromagnetic lattice with easy plane anisotropy. Its dynamics is described via the Heisenberg model. Discrete breathers exist in such a model and represent excitations with locally tilted magnetization....
متن کاملA Multi Plane Model for Natural Anisotropy of Sand
Anisotropy of sand is mainly due to the geometrical arrangement of particles that depends on the orientation of applied load respect to the bedding plane. It is geologically due to micro-fabric created by the arrangement of the particles configured during deposition. Most of the models develop using stress/strain invariants are not capable of identifying this kind of anisotropy. This is mainly ...

Slow magnetic relaxation in mononuclear seven-coordinate cobalt(II) complexes with easy plane anisotropy.
Two mononuclear seven-coordinate cobalt(II) complexes [Co(L)3(NO3)2] (L = 4-tert-butylpyridine, 1; L = isoquinoline, 2) were prepared and structurally analyzed by single-crystal X-ray crystallography. The coordination spheres of 1 and 2 exhibit distorted pentagonal bipyramid geometry. Analysis of their direct-current magnetic data reveals the existence of easy plane anisotropy (D > 0) with a sm...
