Journal ArticleDOI
Enhancement of the high-field critical current density of superconducting MgB2 by proton irradiation
Y. Bugoslavsky,L. F. Cohen,G. K. Perkins,Massimiliano Polichetti,T.J. Tate,Russell M. Gwilliam,A.D. Caplin +6 more
TL;DR: It is shown that modest levels of atomic disorder induced by proton irradiation enhance the pinning of vortices, thereby significantly increasing Jc at high field strengths, and it is anticipated that either chemical doping or mechanical processing should generate similar levels of disorder, and so achieve performance that is technologically attractive in an economically viable way.
Journal ArticleDOI
Vortex dynamics in superconducting MgB2 and prospects for applications.
TL;DR: The results show that naturally occurring grain boundaries are highly transparent to supercurrents, a desirable property which contrasts with the behaviour of the high-temperature superconductors.
Journal ArticleDOI
Flux Pump for HTS Magnets
C Hoffmann,D Pooke,A.D. Caplin +2 more
TL;DR: In this paper, a flux pump based on 2G HTS wire is presented, which can achieve a critical current of 49 A within 112 seconds, which is a state-of-the-art performance for superconducting devices.
Journal ArticleDOI
First Order Magnetic Transition in Doped CeFe 2 Alloys: Phase Coexistence and Metastability
S. B. Roy,G. K. Perkins,M. K. Chattopadhyay,A. K. Nigam,K.J.S. Sokhey,P. Chaddah,A.D. Caplin,L. F. Cohen +7 more
TL;DR: In this article, the first order ferromagnetic to antiferromagnetic (FM) phase transition in doped CeFe alloys is studied with the micro-Hall probe technique.
Journal ArticleDOI
Influence of oxygen stoichiometry on the irreversible magnetization and flux creep in RBa2Cu3O7- delta (R=Y,Tm) single crystals.
A.A. Zhukov,H. Küpfer,G. K. Perkins,L. F. Cohen,A.D. Caplin,S.A. Klestov,H. Claus,V. I. Voronkova,T. Wolf,H. Wühl +9 more
TL;DR: In highly deoxygenated samples, the fishtail feature is observed for practically all temperatures, and points to the importance of oxygen disorder for the pinning and stresses the melting nature of the irreversibility line.
