Distribution of Transport Current in a Type-II Superconductor Studied by Small-Angle Neutron Scattering

The Vortex Lattice of a Type II Superconductors Studied by Small Angle Neutron Scattering

In this laboratory work we will study the vortex lattice VL of a type II superconductor using Small Angle Neutron Scattering SANS. The sample is a single crystal of Nb, a superconductor with a Tc = 9.3 K and lower and upper critical fields of μ0Hc1 = 0.18T and μ0Hc2 = 0.4T, respectively. For external magnetic fields between Hc1 and Hc2 the superconductor is in the so-called intermediate state. ...

Aggregation in ferrofluids studied by Neutron Small Angle Scattering

2014 Neutron Small Angle Scattering has been used to follow processes of particle aggregation in ferrofluids under various conditions of temperature and externally applied magnetic field. Cobalt particles, stabilized in toluene by one of two surfactant materials, showed neutron scattering characteristic of highly aggregated systems. Low temperature quenching in a strong magnetic field caused ph...

Small angle neutron scattering

Small Angle Neutron Scattering (SANS) is a technique that enables to probe the 3-D structure of materials on a typical size range lying from ∼ 1 nm up to ∼ a few 100 nm, the obtained information being statistically averaged on a sample whose volume is ∼ 1 cm3. This very rich technique enables to make a full structural characterization of a given object of nanometric dimensions (radius of gyrati...

Structural characterization of ionic gelator studied by dynamic light scattering and small-angle neutron scattering.

Structural characterization of a hydrogel consisting of an oligomeric electrolyte, poly[pyridinium-1,4-diyliminocarbonyl-1,4-phenylenemethylene chloride] (1-Cl) as an ionic gelator was carried out by static and dynamic light scattering (SLS/DLS) and small-angle neutron scattering (SANS) techniques. All the measurements were performed by changing the concentration and temperature. We have succes...
