Anisotropic superconductivity in the quasi-one-dimensional superconductor VGa
G. Lamura, D. Tay, R. Khasanov +7
The intermetallic quasi-one-dimensional binary superconductor VGa was recently found to exhibit a topologically nontrivial normal state, making it a natural candidate for a…
Depth-dependent study of time-reversal symmetry-breaking in the kagome superconductor VSb
J. N. Graham, C. Mielke, D. Das +21
The breaking of time-reversal symmetry (TRS) in the normal state of kagome superconductors VSb stands out as a significant feature. Yet the extent to which this effe…
Microscopic nature of the charge-density wave in kagome superconductor RbVSb
Jonathan Frassineti, Pietro Bonfà, Giuseppe Allodi +7
The recently discovered vanadium-based kagome metals AVSb (A = K, Rb, Cs) offer the possibility to study the interplay between competing electronic orderings, such as charg…
Intrinsic nature of spontaneous magnetic fields in superconductors with time-reversal symmetry breaking
B. M. Huddart, I. J. Onuorah, M. M. Isah +5
We present a systematic investigation of muon-stopping states in superconductors that reportedly exhibit spontaneous magnetic fields below their transition temperatures due to time…
Fast recovery of the pristine magnetic and structural phases in superconducting LaFeAsOF by Mn/Fe substitution
S. Sanna, P. Carretta, M. Moroni +5
We report on an experimental study of the effect of Mn impurities in the optimally doped LaFeAsOF compound. The results show that a very tiny amount of Mn, of the…
Disentangling superconducting and magnetic orders in NaFe_1-xNi_xAs using muon spin rotation
Sky C. Cheung, Zurab Guguchia, Benjamin A. Frandsen +24
Muon spin rotation and relaxation studies have been performed on a "111" family of iron-based superconductors NaFe_1-xNi_xAs. Static magnetic order was characterized by obtaining t…
