Dynamic nanoscale structural correlations in strontium ruthenate
M. SpaiÄ, R. Spieker, I. BiloniÄ +14
Strontium ruthenate (SrRuO, SRO) has been the subject of intense research as a model quasi-two-dimensional metal with strong electronic correlations and potential exotic mu…
Vortex pinning of BaKBiO investigated by magneto-optical Kerr-effect and magnetization measurements
Soichiro Yamane, Sota Nakamura, Atsutoshi Ikeda +8
Vortex pinning plays a crucial role in determining properties of type-II superconductors. For example, it governs the irreversible magnetic response as well as dissipation caused b…
Tuning charge-transport properties and magnetic order in metallic EuTiO
Xing He, Chiou Yang Tan, Issam Khayr +9
The stoichiometric antiferromagnetic insulator EuTiO is proximate to a ferroelectric phase. Whereas cation substitution has been used as a tuning parameter to introduce charge…
Evidence for rare-region physics in the structural and electronic degrees of freedom of the nickelate LaSrNiO
R. J. Spieker, B. Krohnke, D. Zhai +11
We present a diffuse neutron and x-ray scattering study of structural, spin- and charge-density-wave fluctuations in the electrical insulator LaSrNiO. This lamellar…
Uniaxial strain tuning of polar lattice vibrations in KTaO and SrTiO
I. Khayr, N. Somun, S. Hameed +11
The interplay of electronic and structural degrees of freedom is a prominent feature of many quantum materials and of particular interest in systems with strong ferroelectric fluct…
Nature of the ferromagnet-paramagnet transition in YCaTiO
S. Hameed, I. Khayr, J. Joe +8
Neutron scattering, magnetometry, and muon spin rotation (SR) measurements were performed to investigate the magnetic order and spin dynamics across the ferromagnet-to-paramagn…
