Impact of Disorder on Microscopic Superconducting and Normal‐State Responses in a Kagome Metal

J. N. Graham, S. S. Islam, Gianluca Janka, Andrin Doll et autres

ABSTRACT In , Ta substitution suppresses charge order while nearly doubling superconducting transition temperature . Pronounced diffuse scattering reveals a highly disordered charge‐ordered state. We investigated the impact of this disorder on the superconducting and normal‐state properties using depth‐resolved, magnetic‐field– and pressure‐tuned …

Competing Ordering Modes in the Distorted Quantum Kagome Material Clinoatacamite Cu 2 Cl ( OH ) 3

L. Heinze, C. Kastner, Harald O. Jeschke, M. Reehuis et autres

We have studied the magnetic properties of clinoatacamite Cu 2 Cl ( OH ) 3 , the parent compound of the quantum spin liquid candidate herbertsmithite and a long-standing puzzle among frustrated quantum magnets. As we reveal using density-functional theory, clinoatacamite belongs …

Unraveling spin density wave order in layered nickelates La 3 Ni 2 O 7 and La 2 PrNi 2 O 7 via neutron diffraction

Anonymous, T. J. Hicken, L. Keller, Vladimir Pomjakushin et autres

The observation of pressure-induced superconductivity in two- and three-layer Ruddlesden-Popper nickelates has spurred intense interest in these materials as a platform for exploring unconventional superconductivity. While the ground state of these systems has been shown to exhibit magnetism, the direct determination of …

Single-ion anisotropy driven chiral magnetic order in a spin-1 antiferromagnetic chain

Sheila Vaidya, S. P. M. Curley, Pascal Manuel, J. R. Stewart et autres

Chirality in magnetic systems gives rise to a wide range of exotic phenomena, yet its influence in S = 1 chains remains largely unexplored. Herein, we present a comprehensive experimental study of a chiral antiferromagnetic S = 1 chain, [ Ni ( …

Contrasting impurity-induced magnetism and dynamics in 2 H − MoTe 2

Jonas A. Krieger, I. P. Rusinov, Sourabh Barua, Aris Chatzichristos et autres

We investigate the behavior of interstitial Li + 8 implanted near the surface of 2 H − MoTe 2 using β -detected nuclear magnetic resonance. We find that, unlike the muon, Li + 8 does not show any signature of induced magnetism. …

High-Resolution Timing for Vertex-Reconstructed Muon-Spin Spectroscopy Using Plastic Scintillators and MuTRiG

Konrad Briggl, Maxime Lamotte, Marius Snella Köppel, Jonas A. Krieger et autres

Vertex-reconstructed muon-spin spectroscopy (vx-μSR) based on silicon pixel detectors has recently demonstrated unprecedented lateral resolution and operation at muon stop rates exceeding 400 kHz. However, the intrinsic timing resolution of current silicon pixel detector technology limits the accessible frequency range and restricts …

Spin-liquid-like ground states in the double hydroxyperovskites CuSn(OD)6 and MnSn(OD)6 evidenced by μSR spectroscopy

Moumita Naskar, Anton A. Kulbakov, Kaushick K. Parui, Jonas A. Krieger et autres

Double hydroxide perovskites with magnetic transition-metal ions were recently identified as a unique class of materials that combine magnetic frustration with correlated proton disorder-a prerequisite for quantum-disordered fluctuating magnetic ground states resembling spin liquids. Here we present the results of muon spin …

Vanishing ordered moment in the frustrated triangular lattice antiferromagnet CuNdO2

Jonathan Gaudet, Dalmau Reig‐i‐Plessis, Bogeng Wen, Thomas J. Hicken et autres

We investigate the magnetic ground state of CuNdO 2 , which is a delafossite with a triangular lattice of magnetic Nd 3+ ions that are well separated by non-magnetic Cu spacer layers. From inelastic neutron scattering measurements of the crystal electric field, …
