Short-range correlations in the magnetic ground state of Na4Ir3O8
Rebecca Dally, Tom Hogan, Alex Amato +5
The magnetic ground state of the hyper-kagome lattice in Na4Ir3O8 is explored via combined bulk magnetization, muon spin relaxation, and neutron scattering measurements. A short-ra…
Spectroscopic evidence for negative electronic compressibility in a quasi-three-dimensional spin-orbit correlated metal
Junfeng He, T. Hogan, Thomas R. Mion +20
Negative compressibility is a sign of thermodynamic instability of open or non-equilibrium systems. In quantum materials consisting of multiple mutually coupled subsystems, the com…
The evolution of antiferromagnetic susceptibility to uniaxial pressure in Ba(Fe{1-x}Co{x})2As2
Chetan Dhital, Tom Hogan, Z. Yamani +6
Neutron diffraction measurements are presented measuring the responses of both magnetic and structural order parameters of parent and lightly Co-doped Ba(Fe{1-x}Co{x})2As2 under th…
Effect of carrier concentration on magnetism and magnetic order in the pyrochlore iridates
M. J. Graf, S. M. Disseler, Chetan Dhital +9
We present resistivity, magnetization, and zero field muon spin relaxation (SR) data for the pyrochlore iridate materials NdCaIrO (, and $…
Complex structures of different CaFeAs samples
Bayrammurad Saparov, Claudia Cantoni, Minghu Pan +6
The interplay between magnetism and crystal structures in three CaFeAs samples is studied. For the nonmagnetic quenched crystals, different crystalline domains with var…
