Electron-phonon superconductivity in C-doped topological nodal-line semimetal ZrPt: A muon spin rotation and relaxation (SR) study

A Bhattacharyya, P P Ferreira, K Panda +6

In the present work we demonstrate that C-doped ZrPt is an electron-phonon superconductor (with critical temperature T = 3.7\,K) with a nonsymmorphic topol…

Absence of superconductivity in NbB

F. Abud, L. E. Correa, I. R. Souza +3

A systematic study of the superconducting properties in a series of arc-melted Nb-B samples close to the 1:1 composition was carried out. Powder X-ray diffraction (XRD) shows that…

Two-Dimensional Magnetic Correlations and Partial Long-Range Order in Geometrically Frustrated Sr2YRuO6

E. Granado, J. W. Lynn, R. F. Jardim +1

Neutron diffraction on the double perovskite Sr2YRuO6 with a quasi-face-centered cubic (FCC) lattice of Ru moments reveals planar magnetic correlations that condense into a partial…

Anelastic spectroscopy study of the metal-insulator transition of Nd(1-x)EuxNiO3

F. Cordero, F. Trequattrini, V. B. Barbeta +2

Measurements are presented of the complex dynamic Young's modulus of NdNiO3 and Nd0.65Eu0.35NiO3 through the Metal-Insulator Transition (MIT). On cooling, the modulus presents a na…
