Direct measurement of a remnant Fermi surface in SmB6
Thomas E. Millichamp, David Billington, Hannah C. Robarts +8
The quest to understand the nature of the electronic state in SmB6 has been challenging, perplexing and surprising researchers for over half a century. In the theoretically predict…
Bulk and element specific magnetism of the medium and high entropy Cantor-Wu alloys
D. Billington, A. D. N. James, E. I. Harris-Lee +14
Magnetic Compton scattering, x-ray magnetic circular dichroism spectroscopy and bulk magnetometry measurements are performed on a set of medium (NiFeCo and NiFeCoCr) and high (NiFe…
Extreme Fermi surface smearing in a maximally disordered concentrated solid solution
Hannah C. Robarts, Thomas E. Millichamp, Daniel A. Lagos +13
We show that the Fermi surface can survive the presence of extreme compositional disorder in the equiatomic alloy NiFeCoCr. Our high-resolution…
Vacancies, disorder-induced smearing of the electronic structure, and its implications for the superconductivity of anti-perovskite MgCNi
David Ernsting, David Billington, Thomas E. Millichamp +7
The anti-perovskite superconductor MgCNi was studied using high-resolution x-ray Compton scattering combined with electronic structure calculations. Compton scatt…
Observation of low frequency spin dynamics in INVAR FeNi
Giovanni B Pasquino, Jon W Taylor, Sean R Giblin +3
We present ferromagnetic neutron spin echo measurements and muon spin relaxation (SR) measurements of the spin dynamics in the ordered phase of the metallic alloy INVAR Fe$_{65}…
Calculating electron momentum densities and Compton profiles using the linear tetrahedron method
D. Ernsting, D. Billington, T. D . Haynes +6
A method for computing electron momentum densities and Compton profiles from ab initio calculations is presented. Reciprocal space is divided into optimally-shaped tetrahedra for i…
