Rearrangement of orbitals in KAgF3 due to Kugel-Khomskii mechanism: a Neutron diffraction and Density Functional Theory study
Kacper Koteras, Sebastian Biesenkamp, Paolo Barone +6
The crystal structure of KAgF3 was studied by powder neutron diffraction. KAgF3 exhibits at all temperatures an orthorhombic symmetry in space group Pnma that allows for several di…
Low temperature magnetism of KAgF3
John M. Wilkinson, Stephen J. Blundell, Sebastian Biesenkamp +7
KAgF is a quasi one-dimensional quantum antiferromagnet hosting a series of intriguing structural and magnetic transitions. Here we use powder neutron diffraction, SR spectr…
Strength of Correlations in a Silver Based Cuprate Analogue
Riccardo Piombo, Daniel Jezierski, Henrique Perin Martins +10
AgF2 has been proposed as a cuprate analogue which requires strong correlation and marked covalence. On the other hand, fluorides are usually quite ionic and 4d transition metals t…
Charge ordering mechanism in silver fluoride AgF
Mariana Derzsi, Kamil Tokár, Przemysław Piekarz +1
Using Density Functional Theory, competition between Mott-Hubbard and intervalence charge transfer mechanism of electron localization is revealed in AgF, an important silver an…
Fate of doped carriers in silver fluoride cuprate analogues
Subrahmanyam Bandaru, Mariana Derzsi, Adam Grzelak +2
AgF is a correlated charge-transfer insulator with properties remarkably similar to insulating cuprates which have raised hope that it may lead to a new family of unconventiona…
Epitaxial engineering of flat silver fluorides cuprate analogs
Adam Grzelak, Haibin Su, Xiaoping Yang +3
As-grown AgF2 has a remarkably similar electronic structure as insulating cuprates, but it is extremely electronegative, which makes it hard to handle and dope. Furthermore, buckli…
Dramatic enhancement of spin-spin coupling and quenching of magnetic dimensionality in compressed silver difluoride
Dominik Kurzydłowski, Mariana Derzsi, Paolo Barone +4
Meta-GGA calculations of the ambient and high-pressure polymorphs of silver difluoride indicate that the compression-induced structural changes lead to a 3.5-fold increase in the s…
The silver route to cuprate analogs
Jakub Gawraczyński, Dominik Kurzydłowski, Wojciech Gadomski +13
The parent compound of high-Tc superconducting cuprates is a unique Mott state consisting of layers of spin-1/2 ions arranged on a square lattice and with a record high antiferroma…
Large magnetic anisotropy in quasi one-dimensional spin-1/2 fluoride antiferromagnets with a d(z2)1 ground state
Dominik Kurzydlowski, Wojciech Grochala
Hybrid density functional calculations are performed for a variety of systems containing d9 ions (Cu2+, Ag2+), and exhibiting quasi-one-dimensional magnetic properties. In particul…
