Magnetic Field Structure from Synchrotron Polarization

Total magnetic fields in spiral galaxies, as observed through their total synchrotron emission, are strongest (up to ≃ 30 μG) in the spiral arms. The degree of radio polarization is low; the field in the arms must be mostly turbulent or tangled. Polarized synchrotron emission shows that the resolved regular fields are generally strongest in the interarm regions (up to ≃ 15 μG), sometimes formin...

Polarization of H 2 O Masers in the presence of Velocity and Magnetic Field Gradients

Through polarization observations H 2 O masers are excellent probes of magnetic fields in the maser region. Magnetic field strengths, such as those in the H 2 O masers regions of the envelopes of late-type stars and star-forming regions, are typically determined using a direct relation between the field strength and the observed circular polarization. Here it is shown that velocity and magnetic...

Tracing the Magnetic Field in Molecular Clouds

We discuss how the combination of polarimetry and ion-to-neutral molecular line width ratio measurements permits the determination of the orientation of the magnetic field in the weakly ionized parts of molecular clouds. Polarimetry measurements give the field orientation in the plane of the sky, and the ion-to-neutral molecular line width ratio determines the angle between the magnetic field a...

Melt Flow Control Using Magnetic Fields and Magnetic Field Gradients

Solidification of materials to near net shape is one of the most commonly used and economical methods of manufacturing. Different industries impose different restrictions and design objectives on the solidification process. For example, single crystal growth requires a planar growth front whereas casting requires homogenous material distribution. There are various techniques to control the flow...

Parahydrogen-induced polarization at zero magnetic field.

We use symmetry arguments and simple model systems to describe the conversion of the singlet state of parahydrogen into an oscillating sample magnetization at zero magnetic field. During an initial period of free evolution governed by the scalar-coupling Hamiltonian HJ, the singlet state is converted into scalar spin order involving spins throughout the molecule. A short dc pulse along the z ax...
