Publikováno v: Physical Review B. 106
CeAlGe, a proposed type-II Weyl semimetal, orders antiferromagnetically below 5 K. At 2 K, spin-flop and a spin-flip transitions to less than 1 $\mu_B$/Ce are observed in the $M(H)$ data below 30 kOe, ($\bf{H}\|\bf{a}$ and $\bf{b}$, and 4.3 kOe, $\bf

Critical Current Density of ${\rm YBa}_{2}{\rm Cu}_{3}{\rm O}_{7-\delta}$ Coated Conductors Under High Compression in High Fields
Autor: Damian P. Hampshire, J S Higgins
Publikováno v: IEEE Transactions on Applied Superconductivity. 21:3234-3237
From an engineering standpoint, the magnetic field (B), temperature (T), and strain dependence (e) of the critical current density (JC) in practical superconducting wires/tapes is critical for optimizing device design using superconducting technology

Angular, Temperature, and Strain Dependencies of the Critical Current of DI-BSCCO Tapes in High Magnetic Fields
Autor: Damian P. Hampshire, P. Sunwong, J S Higgins
Publikováno v: IEEE Transactions on Applied Superconductivity. 21:2840-2844
High critical current density (Jc) DI-BSCCO Bi-2223 superconducting tape has been developed by Sumitomo Electric Industries (SEI) using the Controlled Over-Pressure (CT-OP) technique to improve the texturing and densification. Further enhancement of

Probes for investigating the effect of magnetic field, field orientation, temperature and strain on the critical current density of anisotropic high-temperature superconducting tapes in a split-pair 15 T horizontal magnet
Autor: P. Sunwong, J S Higgins, Damian P. Hampshire
Publikováno v: Review of scientific instruments, 2014, Vol.85(6), pp.065111 [Peer Reviewed Journal]
We present the designs of probes for making critical current density (Jc) measurements on anisotropic high-temperature superconducting tapes as a function of field, field orientation, temperature and strain in our 40 mm bore, split-pair 15 T horizont

Formation of microstructure in polymer blends
Autor: C. B. Bucknall, J. S. Higgins, A. Keller, A. H. Windle
Publikováno v: Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences. 348:131-147
The microstructure and morphology of a mixture of polymeric materials depends on factors in both the thermal and rheological history of a sample as well as on its equilibrium thermodynamics. Concentrating largely on systems which are partly miscible

The critical current density of grain boundary channels in polycrystalline HTS and LTS superconductors in magnetic fields
Autor: P. Sunwong, Y. Tsui, Mark J. Raine, Damian P. Hampshire, J. S. Higgins
Publikováno v: Superconductor science and technology, 2013, Vol.26(9), pp.095006 [Peer Reviewed Journal]
Flux pinning scaling laws were developed to explain the observed increase in the critical current density Jc caused by increased density of grain boundaries in polycrystalline low temperature superconductors (LTS) such as Nb3Sn. For four decades they
