Net Magnetization and Inhomogeneous Magnetic Order in a High-Tc Nickelate Superconductor
Alexander J. Grutter, Nurul Fitriyah, Brian B. Maranville +10
High-temperature and high-magnetic-field-induced re-entrant superconductivity has been discovered in the infinite-layer nickelate (SECNO). In…
Niobium's intrinsic coherence length and penetration depth revisited using low-energy muon spin spectroscopy and secondary-ion mass spectrometry
Ryan M. L. McFadden, Jonathan W. Angle, Eric M. Lechner +7
We report direct, simultaneous measurements of the London penetration depth () and Bardeen-Cooper-Schrieffer (BCS) coherence length () in oxygen-doped niobium, with impur…
Cu-spin Correlation in the Electron-overdoped High-Tc Cuprate Thin Films of La_2-x_Ce_x_CuO_4_ Probed by Low-energy Muons
S. E. Park, Y. Kawai, A. Suter +7
We investigated the Cu-spin correlation in the overdoped regime of the electron-doped high-Tc cuprate thin films of La_2-x_Ce_x_CuO_4_, changing the reduction condition from muon s…
Surface-Localized Magnetic Order in RuO2 Thin Films Revealed by Low-Energy Muon Probes
Akashdeep Akashdeep, Sachin Krishnia, Jae-Hyun Ha +12
Ruthenium dioxide (RuO2) has recently emerged as a candidate altermagnet, yet its intrinsic magnetic ground state, particularly in thin films, remains debated. This study aims to c…
Microwave Spectroscopy of the Muonium Fine Structure Interval
Philipp Blumer, Gianluca Janka, Svenja Geissmann +8
We report a microwave spectroscopy measurement of the muonium fine structure transition, yielding a transition frequency of , in ag…
Implantation studies of low-energy positive muons in niobium thin films
Ryan M. L. McFadden, Andreas Suter, Leon Ruf +5
Here we study the range of keV positive muons implanted in NbO( nm)/Nb( nm)/SiO(300 nm)/Si [ = 3.6 nm, 3.3 nm; = 42.0 nm, 60.1 nm] thin films using l…
Unconventional polaronic ground state in superconducting LiTiO
Zubia Hasan, Grace A. Pan, Harrison LaBollita +23
Geometrically frustrated lattices can display a range of correlated phenomena, ranging from spin frustration and charge order to dispersionless flat bands due to quantum interferen…
New Frontiers in Muon-Spin Spectroscopy Using Si-Pixel Detectors
Heiko Augustin, Niklaus Berger, Andrin Doll +9
The study of novel quantum materials relies on muon-spin rotation, relaxation, or resonance (\mSR) measurements. Yet, a fundamental limitation persists: many of these materials can…
Coherent microwave control of coupled electron-muon centers
Andrin Doll, Chennan Wang, Thomas Prokscha +2
Coherent control by means of tailored excitation is a key to versatile experimental schemes for spectroscopic investigation and technological utilization of quantum systems. Here w…
Complex Magnetic Ordering in Candidate Topological Superconductors
Purnima P. Balakrishnan, Hemian Yi, Zi-Jie Yan +13
The search for chiral topological superconductivity in magnetic topological insulator (TI)-FeTe heterostructures is a key frontier in condensed matter physics, with potential appli…
Advanced muon-spin spectroscopy with high lateral resolution using Si-pixel detectors
Lukas Mandok, Pascal Isenring, Heiko Augustin +7
Muon-spin spectroscopy at continuous sources has stagnated at a stopped muons rate of ~40 kHz for the last few decades. The major limiting factor is the requirement of a single muo…
