Surface spin-flop and discommensuration transitions in antiferromagnets
Phase diagrams as a function of anisotropy D and magnetic field H are obtained for discommensurations and surface states for an antiferromagnet in which H is parallel to the easy axis, by modeling it using the ground states of a one-dimensional chain of classical XY spins. A surface spin-flop phase exists for all D, but the interval in H over which it is stable becomes extremely small as D goes...
متن کاملSuperstructures at low spin - high spin transitions
In many transition metal compounds, in particular those containing Fe and Co, there occur spin-state transitions between low-spin and high-spin (or intermediate-spin) states. We show that typical interactions between similar spin-state ions are short-range repulsion, and long-range interaction which can have a different sign depending on the elastic anisotropy of the lattice and on the directio...
متن کاملAntiferromagnetic spin flop and exchange bias
The effect of the antiferromagnetic spin flop on exchange bias has been investigated in antiferromagnetic (MnF2) –ferromagnetic ~Fe! bilayers. Cooling and measuring in fields larger than the antiferromagnetic spinflop field, HSF , causes an irreversible reduction of the magnitude of the exchange bias field, HE . This indicates that, contrary to what is normally assumed, the interface spin struc...
متن کاملSpin-orbit interaction in bent carbon nanotubes: resonant spin transitions.
We develop an effective tight-binding Hamiltonian for spin-orbit (SO) interaction in bent carbon nanotubes (CNT) for the electrons forming the π bonds between the nearest neighbor atoms. We account for the bend of the CNT and the intrinsic spin-orbit interaction which introduce mixing of π and σ bonds between the p(z) orbitals along the CNT. The effect contributes to the main origin of the SO c...
متن کاملAngular dependence of the spin-flop transition and a possible structure of the spin-flop phase of Gd5Ge4
The angular dependence of the spin-flop transition in Gd5Ge4 has been examined by magnetization measurements of a single crystal. When the magnetic field vector is tilted away from the antiferromagnetic easy axis (c axis) toward the b axis, the spin-flop transition always remains first order in nature. However, when the field vector is tilted away from the c axis toward the a axis, the first or...
