Gradual localization of 5f states in orthorhombic UTX ferromagnets - polarized neutron diffraction study of Ru substituted UCoGe

Michal Valiska, Jiri Pospisil, Anne Stunault +13

We report on a microscopic study of the evolution of ferromagnetism in the Ru substituted ferromagnetic superconductor (FM SC) UCoGe crystallizing in the orthorhombic TiNiSi-type s…

A neutron diffraction study from 6 to 293 K and a macroscopic-scale quantum theory of the hydrogen bonded dimers in the crystal of benzoic acid

François Fillaux, A. Null Cousson

The crystal of benzoic acid is comprised of tautomeric centrosymmetric dimers linked through bistable hydrogen bonds. Statistical disorder of the bonding protons is excluded by neu…

Evidence of macroscopically entangled protons in a mixed isotope crystal of KH $_{p}$ D $_{1 - p}$ CO $_{3}$

François Fillaux, Alain Cousson, Matthias J. Gutmann

We examine whether protons and deuterons in the crystal of KH $_{0.76}$ D $_{0.24}$ CO $_{3}$ at 300 K are particles or matter waves. The neutron scattering function measured over a broad…

The macroscopic quantum behavior of protons in the KHCO_3 crystal: Theory and experiments

François Fillaux, Alain Cousson, Matthias J. Gutmann

For hydrogen bonded crystals exhibiting proton transfer along hydrogen bonds, namely $O1 - H ... O2 ⟷ O1 ... H - O2$ , there is a dic…
