Local magnetic properties of the rare-earth intermetallics $R$ Mn $_{2}$ Ge $_{2}$ ( $R$ =Ce, Pr, Nd)

N. P. Bentley, T. L. Breeze, A. Hernández-Melián +9

We present an investigation of the rare-earth intermetallic materials, $R$ Mn $_{2}$ Ge $_{2}$ ( $R$ =Ce, Pr, Nd), reported to host a lattice of skyrmionic bubbles at room temperature. The m…

Re-evaluating photoluminescent defects in Cu $_{2}$ O

Alistair Brewin, Matthew P A Jones, Stewart J Clark

Defects in cuprous oxide (Cu $_{2}$ O) strongly influence its performance in applications ranging from photovoltaics to emerging quantum technologies based on Rydberg excitons where mi…

From Densities to Potentials: Benchmarking Local Exchange-Correlation Approximations

Visagan Ravindran, Clio Johnson, Neil D. Drummond +2

Using the Kohn-Sham (KS) inversion method of Hollins et al. [J. Phys.: Condens. Matter 29, 04LT01 (2017)], we invert densities from variational and diffusion quantum Monte Carlo (Q…

Local Exchange-Correlation Potentials by Density Inversion in Solids

Visagan Ravindran, Nikitas I. Gidopoulos, Stewart J. Clark

Following Hollins et al. [J. Phys.: Condens. Matter 29, 04LT01 (2017)], we invert the electronic ground state densities for various semiconducting and insulating solids calculated…

Magnetism in $M_{1/3}$ NbS $_{2}$ ( $M$ = Fe, V, Mn): insight into intercalated transition-metal dichalcogenides using $I^¼$ SR

N. P. Bentley, T. L. Breeze, A. HernÃ¡ndez-MeliÃ¡n +8

We present the results of muon-spin relaxation ( $I^¼$ SR) measurements of the static and dynamic magnetism of $M_{1/3}$ NbS $_{2}$ ( $M$ = Fe, V, Mn), three intercalated transition-metal…

Muon spectroscopy investigation of anomalous dynamic magnetism in NiI $_{2}$

T. L. Breeze, B. M. Huddart, A. HernÃ¡ndez-MeliÃ¡n +9

We present the results of muon-spin relaxation ( $I^¼^{+}$ SR) measurements of the van der Waals magnet NiI $_{2}$ , which probe magnetic phase transitions at $T_{N1} = 73$ ~K and $…
