Theory and Practice of Neutron Diffraction

Theory of Neutron Diffraction from the Vortex Lattice in UPt3

Neutron scattering experiments have recently been performed in the superconducting state of UPt3 to determine the structure of the vortex lattice. The data show anomalous field dependence of the aspect ratio of the unit cell in the B phase. There is apparently also a change in the effective coherence length on the transition from the B to the C phases. Such observations are not consistent with ...

Schwab's Practical Theory: Integrate of Theory and Practice

The emergence of re-conceptualism in the field of curriculum studies caused a large rotation of identity in this field. The book titled "understanding of curriculum" by William Pinar may be considered the most outstanding work in the field. In this book, movement which affected pre re-conceptualist, are introduced as the traditional type and it is believed the new curriculum discourses should b...

Neutron Diffraction Experiments

This ISEN award supported research toward improving the energy efficiency of actuators. The focused research objective was to develop next-generation shape memory alloy (SMA) models and structures, to demonstrate this new technology in targeted near-term applications on airplanes. Two research avenues were pursued to enable development of this new technology: 1) neutron diffraction experiments ...

Magnetic structure of greigite (Fe3S4) probed by neutron powder diffraction and polarized neutron diffraction

[1] We have investigated greigite (Fe3S4) using a combination of neutron powder diffraction and polarized neutron diffraction to give the first unambiguous assignment of its magnetic structure. Our results confirm that greigite has a collinear ferrimagnetic structure with antiferromagnetic coupling between the tetrahedral (A) and octahedral (B) sites. Our analysis also indicates that greigite d...
