Magnetic Quantum Criticality inside the Superconducting State Revealed by Penetration Depth Scaling with Local
Yusuke Iguchi, Kaede Inoh, Ryosuke Koizumi +1
We demonstrate a magnetic quantum critical point embedded within the superconducting state of Zn-doped CeCoIn, revealed by a pronounced peak in the magnetic penetration depth a…
Visualizing Vortex Cluster Dynamics in the Weak Type-II Superconductor CaSb
Yusuke Iguchi, Nabhanila Nandi, Mohamed Oudah
Scanning SQUID imaging of CaSb reveals dense vortex clusters with enhanced boundary susceptibility and suppressed internal vortex motion, which features inconsistent with both…
Vortex Motion Induced Losses in Tantalum Resonators
Faranak Bahrami, Matthew P. Bland, Nana Shumiya +17
Tantalum (Ta) based superconducting circuits have been demonstrated to enable record qubit coherence times and quality factors, motivating a careful study of the microscopic origin…
Magnetic edge fields in UTe near zero background fields
Yusuke Iguchi, Huiyuan Man, S. M. Thomas +5
Chiral superconductors are theorized to exhibit spontaneous edge currents. Here, we found magnetic fields at the edges of UTe, a candidate odd-parity chiral superconductor, tha…
In-situ local imaging of ferromagnetism and superconductivity in RbEuFeAs
Huiyuan Man, Yusuke Iguchi, Jin-Ke Bao +2
The coexistence of superconductivity and ferromagnetism is an intrinsically interesting research focus in condensed matter physics but the study is limited by low superconducting (…
Scanning SQUID study of ferromagnetism and superconductivity in infinite-layer nickelates
Ruby A. Shi, Bai Yang Wang, Yusuke Iguchi +6
Infinite-layer nickelates SrNiO ( = La, Pr, Nd) are a class of superconductors with structural similarities to cuprates. Although long-range antiferromagnet…
Anomalous superfluid density in a disordered charge density wave material: Pd-intercalated ErTe
Yusuke Iguchi, Joshua A. Straquadine, Chaitanya Murthy +4
We image local superfluid density in single crystals of Pd-intercalated ErTe below the superconducting critical temperature, , well below the onset temperature, ,…
Superconducting Penetration Depth Through a Van Hove Singularity: SrRuO Under Uniaxial Stress
Eli Mueller, Yusuke Iguchi, Fabian Jerzembeck +12
In the unconventional superconductor SrRuO, uniaxial stress along the direction tunes the Fermi level through a Van Hove singularity (VHS) in the density of states,…
