The Thermodynamic Properties of Polarized Metallic Nanowire in the Presence of Magnetic Field

In this article, the second quantization method has been used to investigate some thermodynamic properties of spin-polarized metallic nanowire in the presence of magnetic field at zero temperature. We have been observed that in different magnetic field, the equilibrium energy of system increases as the density increases. The spin-polarization parameter corresponding to the equilibrium state of ...

Quantum Interference Control of Ballistic Magneto- resistance in a Magnetic Nanowire Containing Two Atomic- Size Domain Walls

The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...

Amplitudes for magnon scattering by vortices in two–dimensional weakly easy–plane ferromagnets

We study magnon modes in the presence of a vortex in a circular easy–plane ferromagnet. The problem of vortex–magnon scattering is investigated for partial modes with different values of the azimuthal quantum number m over a wide range of wave numbers. The analysis was done by combining analytical and numerical calculations in the continuum limit with numerical diagonalization of adequately lar...

Spin-ordering and magnon collective modes for two-dimensional electron lattices in strong magnetic fields.

We study the spin-ordering and the magnon collective modes of the twodimensional Wigner crystal state at strong magnetic fields. Our work is based on the Hartree-Fock approximation for the ground state and the timedependent Hartree-Fock approximation for the collective modes. We find that the ground state is ferromagnetic, i.e., that all spins are aligned at T = 0 even when the electronic g-fac...

Internal modes and magnon scattering on topological solitons in two--dimensional easy--axis ferromagnets

We study the magnon modes in the presence of a topological soliton in a two-dimensional Heisenberg easy-axis ferromagnet. The problem of magnon scattering on the soliton with arbitrary relation between the soliton radius R and the ‘‘magnetic length’’ D0 is investigated for partial modes with different values of the azimuthal quantum numbers m. Truly local modes are shown to be present for all v...
