We present the derivation of the macroscopic equations for uniaxial ferrogels. In addition to the usual hydrodynamic variables for gels we introduce the magnetization and the relative rotations between the magnetization and the network as macroscopic variables. The relative rotations introduced here for a system with magnetic degrees of freedom are the analog of the relative rotations introduce...

We study the quantum phase transition occurring in an infinite homogeneous system of spin 1/2 fermions in a non-relativistic context. As an example we consider neutrons interacting through a simple spin-spin Heisenberg force. The two critical values of the coupling strength — signaling the onset into the system of a finite magnetization and of the total magnetization, respectively — are found a...

The magnetic ordering and the interlayer exchange coupling in Mn and Fe/Mn wedge structures grown epitaxially on Fe(001) whisker substrates were investigated using scanning electron microscopy with polarization analysis (SEMPA). In bare Mn/Fe(001) samples, the magnetization of the top Mn layer is collinear with the Fe magnetization, and oscillates between ferromagnetic and antiferromagnetic ali...

Spin-orbit coupling in ferromagnets gives rise to the anomalous Hall effect and the anisotropic magnetoresistance, both of which can be used to create spin-transfer torques in a similar manner as the spin Hall effect. In this paper, we show how these effects can be used to reliably switch perpendicularly magnetized layers and to move domain walls. A drift-diffusion treatment of the anomalous Ha...

the permeability and the power losses are very important properties of non-oriented electrical sheets. the existence of a crystallographic easy magnetization plane and direction makes the distribution of grain orientations (texture) the most important factor in the improvement of the quality of a soft magnetic material [1]. the optimum texture is a fibre texture in which all the grains have a <...

Sound attenuation and velocity in nickel single crystals have been studied as function of frequency (10 to 250 MHz), temperature, strength and direction of external magnetic field along , (110> and , for the three pure wave modes propagating along . The observed effects are found to be specific for each combination of sound mode and field direction, and especially interesting for...

The magnetic flux leakage (MFL) detection technique is applied to the of weld defects, such as cracks and pores. As has a distinct structure, there are differences in magnetization path field intensity under different directions. According surveys, suitable direction can significantly enhance rates small-sized defects by stimulating stronger signal defect leakage. In this study, ANSYS finite el...
