Field-induced magnetic and structural domain alignment inPrO2

Flow and magnetic field induced collagen alignment.

A straightforward technique to align thin collagen gels is presented. This technique requires only collagen solution, surface-modified magnetic beads, a small magnet, and an incubator. As such, this is the only collagen alignment technique that requires no specialized equipment. The collagen gels are imaged with confocal reflectance microscopy, and degree of alignment is quantitatively assessed...

Magnetic-field-induced Griffiths phase versus random-field criticality and domain wall susceptibility of Fe0.47Zn0.53F2.

Magnetic-field-induced Alignment and Instabilities in Ordered Colloids of Tobacco Mosaic Virus

Magnetic fields have been used to produce well aligned nematic liquid crystalline and colloidal crystalline samples of nearly monodisperse tobacco mosaic virus (TMV). Hydrodynamic instabilities induced by reorientation in a magnetic field have been studied in the well aligned nematic liquid crystalline samples.

Dynamics of the magnetic field-induced first order magnetic-structural phase transformation of Gd5(Si0.5Ge0.5)4

The system Gd5(SixGe1−x)4 for 0.4⩽x⩽0.5 has been shown to have an unusual first order, coupled magnetic-structural phase transformation at the Curie temperature. Above the transformation temperature Tc, the material is paramagnetic with a monoclinic structure; below Tc, it is ferromagnetic with an orthorhombic structure. Another unusual feature of this phase transformation is that an applied ma...

Rapid alignment of velocity and magnetic field in magnetohydrodynamic turbulence.

We show that local directional alignment of the velocity and magnetic field fluctuations occurs rapidly in magnetohydrodynamics for a variety of parameters and is seen both in direct numerical simulations and in solar wind data. The phenomenon is due to an alignment between magnetic field and gradients of either pressure or kinetic energy, and is similar to alignment of velocity and vorticity i...
