Journal ArticleDOI
Interplay between superconductivity and ferromagnetism in crystalline nanowires
Jian Wang,Meenakshi Singh,Mingliang Tian,Nitesh Kumar,Nitesh Kumar,Bangzhi Liu,Chuntai Shi,Chuntai Shi,Jainendra K. Jain,Nitin Samarth,Thomas E. Mallouk,Moses H. W. Chan +11 more
TL;DR: In this paper, a single-crystal ferromagnetic cobalt nanowires sandwiched between superconducting electrodes was found to attain zero resistance at low temperatures, and the transition to incomplete superconductivity was foreshadowed by a strikingly large and sharp resistance peak near the super-conducting transition temperature of the electrodes.
Journal ArticleDOI
Controllable template synthesis of superconducting Zn nanowires with different microstructures by electrochemical deposition.
TL;DR: The superconductivity shows a clear crossover from bulklike to quasi-1D behavior, as evidenced by residual low-temperature resistance, when the diameter of the wires is reduced to 70 nm (20 times smaller than the bulk coherence length).
Journal ArticleDOI
Penetrating the oxide barrier in situ and separating freestanding porous anodic alumina films in one step.
Mingliang Tian,S. Y. Xu,Jinguo Wang,Nitesh Kumar,E. Wertz,Qi Li,Paul M. Campbell,Moses H. W. Chan,Thomas E. Mallouk +8 more
TL;DR: A simple method for penetrating the barrier layer of an anodic aluminum oxide (AAO) film and for detaching the AAO film from residual Al foil was developed by reversing the bias voltage in situ after the anodization process is completed.
Journal ArticleDOI
Suppression of superconductivity in zinc nanowires by bulk superconductors.
TL;DR: In this article, the superconductivity of Zn wires of 40 nm diameter is suppressed either completely or partially by superconducting electrodes when the electrodes are driven into their normal state by a magnetic field.
Journal ArticleDOI
Observation of superconductivity in granular bi nanowires fabricated by electrodeposition.
Mingliang Tian,Jinguo Wang,Nitesh Kumar,Tianheng Han,Yoji Kobayashi,Ying Liu,Thomas E. Mallouk,Moses H. W. Chan +7 more
TL;DR: Analysis of the structural and transport data indicates that the superconductivity in granular Bi nanowires probably arises from grain boundary areas where there are structural reconstructions between the grains showing a preferred orientation within a small angular distribution.
