Robustness of superconducting properties to transition metal substitution and impurity phases in Fe1-xVxSe

Franziska K. K. Kirschner, Daniel N. Woodruff, Matthew J. Bristow +4

We have performed transverse- and zero-field muon spin rotation/relaxation experiments, as well as magnetometry measurements, on samples of Fe1-xVxSe and their Li+NH3 intercalates…

Magnetic Monopole Noise

Ritika Dusad, Franziska K. K. Kirschner, Jesse C. Hoke +6

Magnetic monopoles are hypothetical elementary particles exhibiting quantized magnetic charge $m_{0} = \pm (h / μ_{0} e)$ and quantized magnetic flux $Φ_{0} = \pm h / e$ . A classic proposal for de…

Evidence for $J_{eff} = 0$ ground state and defect-induced spin glass behaviour in the pyrochlore osmate Y $_{2}$ Os $_{2}$ O $_{7}$

N. R. Davies, C. V. Topping, H. Jacobsen +14

We present AC and DC magnetometry, heat capacity, muon spin relaxation ( $μ$ SR) and resonant inelastic X-ray scattering (RIXS) studies of the pyrochlore osmate Y $_{2}$ Os $_{2}$ O $_{7}$ . We…

Spin Jahn-Teller antiferromagnetism in CoTi $_{2}$ O $_{5}$

Franziska K. K. Kirschner, Roger D. Johnson, Franz Lang +5

We have used neutron powder diffraction to solve the magnetic structure of orthorhombic CoTi $_{2}$ O $_{5}$ , showing that the long-range ordered state below 26 K identified in our muon-s…

Observation of a crossover from nodal to gapped superconductivity in Lu $_{x}$ Zr $_{1 - x}$ B $_{12}$

Franziska K. K. Kirschner, Nikolay E. Sluchanko, Vladimir B. Filipov +4

We have determined the superconducting and magnetic properties of four samples of Lu $_{x}$ Zr $_{1 - x}$ B $_{12}$ ( $x = 0.04$ , $0.07$ , $0.17$ , and $0.8$ ) using muon spin rotation ( $μ$ SR) an…

Multigap superconductivity in RbCa2Fe4As4F2 investigated using muSR measurements

D. T Adroja, F. K. K. Kirschner, F. Lang +6

The superconducting properties of the recently discovered double Fe $_{2}$ As $_{2}$ layered high- $T_{c}$ superconductor RbCa $_{2}$ Fe $_{4}$ As $_{4}$ F $_{2}$ with $T_{c} \approx$ 30~K have been investiga…
