Micromagnetic Simulations on the Dependence of Gilbert Damping on Domain Wall Velocities in Magnetic Nanowires [PDF]
, 2006 he dependence of damping on domain wall motion and velocity in Permalloy nanowires is presented. The domain wall motion in isolated two micron long Permalloy nanowires, with a rectangular cross-section 10 nm thick and 100 nm wide, is simulated using the ...

Nonlinear dielectric response in ferroelectric thin films
Boletín de la Sociedad Española de Cerámica y Vidrio, 2004 Electrical permittivity dependence on electric external bias field was investigated in PZT thin films. The results revealed the existence of two mechanisms contributing to the electrical permittivity. The first one was related to the domain reorientation,

Domain walls within domain walls in wide ferromagnetic strips
, 2015 We carry out large-scale micromagnetic simulations which demonstrate that due to topological constraints, internal domain walls (Bloch lines) within extended domain walls are more robust than domain walls in nanowires.

Orientation and temperature dependence of domain wall properties in FePt [PDF]
, 2007 An investigation of the orientation and temperature dependence of domain wall properties in FePt is presented. The authors use a microscopic, atomic model for the magnetic interactions within an effective, classical spin Hamiltonian constructed on the ...

Domain walls are diamagnetic [PDF]
Physics Letters B, 1996 It is shown that contrary to a recent claim in the literature, the domain walls made of scalar field are diamagnetic due to presence of massless fermionic modes on the wall. The diamagnetism vanishes at high temperature. Thus the domain walls could produce no effect on a primordial magnetic field in the early universe.
