Magnetic domain-walls and the relaxation method
نویسنده
چکیده
A domain is a region in a ferromagnetic material with the magnetization along a given direction. A magnetic material contains many domains with different magnetizations pointing in different directions in order to minimize the total magnetostatic energy. Regions with different orientations of their magnetization can be close to one another albeit with a boundary called a domain wall (containing typically about 10 – 10 atoms). Saturation occurs when all these regions align along some common direction imposed an external applied field, the total magnetization reaching its largest value Ms. The width of a domain wall is equal to π √

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...
متن کاملMonte Carlo studies of slow relaxation in diluted antiferromagnets.
Monte Carlo simulations of diluted Ising-type antiferromagnets in a uniform external magnetic field in three dimensions show rather strong irreversibilities in the magnetization and a slow relaxation of the remanent magnetization of the domain state. A detailed investigation of the domain state and its relaxation shows that for low temperatures domains are strongly pinned at vacancies and that ...
متن کاملEstimation of Domain Size in Nano-ferroelectrics from Nmr T1 Measurements
The spin lattice relaxation of I = 3/2 quadrupolar spin system due to domain walls in order-disorder ferroelectrics has been studied and a general method is proposed for the measurement of domain width in nano ferroelectrics. Based on the fact that electric polarization undergoes spiral orientation as one moves from one domain to the other, it is assumed that at low temperatures the spins at an...
متن کاملTunable Quantum Tunneling of Magnetic Domain Walls
Perhaps the most anticipated, yet experimentally elusive, macroscopic quantum phenomenon 1 has been spin tunneling in a ferromagnet 2 , which may be formulated in terms of domain wall tunneling 3,4. One approach is to focus on mesoscopic systems where the number of domain walls is finite and the motion of a single wall has measurable consequences. Research of this type includes magnetotransport...
متن کاملDomains, domain walls and the coercive field of amorphous ferromagnets
2014 Magnetic properties of the hysteresis loop of magnetostrictive amorphous ferromagnetic alloys are predominantly determined by the magnetoelastic coupling energy between the spontaneous magnetization and internal stresses. Domain structures as well as the pinning of domain walls are governed by long-range and shortrange stresses, respectively. As sources of elastic stresses we have detected...
