Spontaneous superconducting diode effect in non-magnetic Nb/Ru/SrRuO topological junctions
M. S. Anwar, T. Nakamura, R. Ishiguro +5
Non-reciprocal electronic transport in a material occurs if both time reversal and inversion symmetries are broken. The superconducting diode effect (SDE) is an exotic manifestatio…
A Review of Electronic Transport in Superconducting SrRuO Junctions
Muhammad Shahbaz Anwar, Jason W. A. Robinson
We review electronic transport in superconducting junctions with SrRuO. Transport measurements provide evidence for chiral domain walls and, therefore, chiral superconducti…
Gate-controlled conductance of superconducting NbN nanowires: coherent quantum phase-slips or Coulomb blockade?
M. S. Anwar, J. C. Fenton
Coherent quantum phase slips are expected to lead to a blockade of dc conduction in sufficiently narrow superconducting nanowires below a certain critical voltage. We present measu…
Spontaneous emergence of Josephson junctions in homogeneous rings of single-crystal Sr2RuO4
Yuuki Yasui, Kaveh Lahabi, Victor Fernández Becerra +7
The chiral p-wave order parameter in SrRuO would make it a special case amongst the unconventional superconductors. A consequence of this symmetry is the…
Novel highest-Tc superconductivity in two-dimensional Nb2C MXene
Zaheer Ud Din Babar, M. S. Anwar, Muhammad Mumtaz +4
Currently, superconductivity in two-dimensional (2D) materials is a hot topic of research owing to their potential technological applications. Here, we report observation of superc…
Anomalous anisotropic behaviour of spin-triplet proximity effect in Au/SrRuO/SrRuO junctions
M. S. Anwar, M. Kunieda, R. Ishiguro +6
Spin-polarized supercurrents can be generated with magnetic inhomogeneity at a ferromagnet/spin-singlet-superconductor interface. In such systems, complex magnetic inhomogeneity ma…
Observation of superconducting gap spectra of long-range proximity effect in Au/SrTiO/SrRuO/SrRuO tunnel junctions
M. S. Anwar, M. Kunieda, R. Ishiguro +6
We observe an unconventional superconducting minigap induced into a ferromagnet SrRuO from a spin-triplet superconductor SrRuO using a Au/SrTiO/SrRuO/SrRuO$…
Emergence of Quantum Phase-Slip Behaviour in Superconducting NbN Nanowires: DC Electrical Transport and Fabrication Technologies
N. G. N. Constantino, M. S. Anwar, O. W. Kennedy +3
Superconducting nanowires undergoing quantum phase-slips have potential for impact in electronic devices, with a high-accuracy quantum current standard among a possible toolbox of…
Little-Parks oscillations with half-quantum fluxoid features in Sr2RuO4 micro rings
Yuuki Yasui, Kaveh Lahabi, Muhammad Shahbaz Anwar +5
In a micro ring of a superconductor with a spin-triplet equal-spin pairing state, a fluxoid, a combined object of magnetic flux and circulating supercurrent, can penetrate as half-…
Induced ferromagnetic moment at the interface between epitaxial SrRuO film and SrRuO single crystal
Seung Ran Lee, Muhammad Shahbaz Anwar, Yeong Jae Shin +6
SrRuO (SRO113) is an important material for device physics particularly as one of the best metallic oxide electrodes for ferroelectric devices. This oxide has moderate electron…
Anomalous switching in Nb/Ru/Sr2RuO4 topological junctions by chiral domain wall motion
M. S. Anwar, Taketomo Nakamura, S. Yonezawa +4
A spontaneous symmetry breaking in a system often results in domain wall formation. The motion of such domain walls is utilized to realize novel devices like racetrack-memories, in…
