MICROMAGNETISM IN URu2Si2 AND HIGH TEMPERATURE SUPERCONDUCTORS
It has been proposed, that unconventional density waves (UDW) are possible candidates for systems with hidden order parameter. Unlike in conventional density waves, no periodic modulation of either the charge-, or the spin-density is present in UDW, in spite of a clear thermodynamic signal. Although the unconventional spin density wave (USDW) has been suggested for the ”antiferromagnetic” phase...
متن کاملOn Stabilized Finite Element Methods in Relaxed Micromagnetism
The magnetization state of a ferromagnetic body is given as the solution of a non-convex variational problem. A relaxation of this model by convexifying the energy density resolves essential macroscopic information that applied physicists and engineers are after. The numerical analysis of the relaxed model faces a nonlinearly constrained convex but degenerated energy functional in mixed formula...
متن کاملMicromagnetism and high temperature coercivity of MnBiÕAl multilayers
The micromagnetic properties of multilayered MnBi/Al films have been investigated and compared to pure MnBi thin films. Pure MnBi films reveal an anomalous increase of the high temperature coercivity, which has been explained on the basis of a hybrid domain wall pinning model. The multilayer-type preparation of MnBi/Al thin films results in significantly reduced MnBi particle size of approximat...
متن کاملFinite element micromagnetism simulations on the magnetization reversal behaviors of cobalt nanotubes.
In this paper, we have used the finite element micromagnetism theory to simulate the magnetization (M) reversal behaviors of cobalt nanotubes with different lengths (L = 400, 600, 800 and 1000 nm). The inner radius and outer radius of nanotubes are 50 nm and 100 nm respectively. The simulation results show that all the nanotubes exhibit significantly anisotropic behaviors: the easy magnetizatio...
متن کاملStabilization Methods in Relaxed Micromagnetism
The magnetization of a ferromagnetic sample solves a non-convex variational problem, where its relaxation by convexifying the energy density resolves relevant macroscopic information. The numerical analysis of the relaxed model has to deal with a constrained convex but degenerated, nonlocal energy functional in mixed formulation for magnetic potential u and magnetization m. In [C. Carstensen an...
