Superconductivity-driven ferromagnetism and spin manipulation using vortices in the magnetic superconductor EuRbFe4As4
Shigeyuki Ishida, Daniel Kagerbauer, Sigrid Holleis +8
Magnetic superconductors are specific materials exhibiting two antagonistic phenomena, superconductivity and magnetism, whose mutual interaction induces various emergent phenomena,…
Unique defect structure and advantageous vortex pinning properties in superconducting CaKFe4As4
Shigeyuki Ishida, Akira Iyo, Hiraku Ogino +10
The lossless current-carrying capacity of a superconductor is limited by its critical current density (Jc). A key to enhance Jc towards real-life applications is engineering defect…
Coexisting spin resonance and long-range magnetic order of Eu in EuRbFeAs
K. Iida, Y. Nagai, S. Ishida +14
Magnetic excitations and magnetic structure of EuRbFeAs were investigated by inelastic neutron scattering (INS), neutron diffraction, and random phase approximation (RPA) c…
Nanoscale Magnetic Compasses
Hidetsugu Shiozawa, Desai Zhang, Michael Eisterer +4
We have synthesized nanoscale magnetic compasses with high yield. These ferromagnetic iron carbide nano-particles, which are encapsulated in a pair of parallel carbon needles, chan…
Doping-dependent critical current properties in K, Co, and P-doped BaFe2As2 single crystals
Shigeyuki Ishida, Dongjoon Song, Hiraku Ogino +5
In order to establish the doping dependence of the critical current properties in the iron-based superconductors, the in-plane critical current density (Jc) of BaFe2As2-based super…
Performance Boost in Industrial Multifilamentary Nb3Sn Wires due to Radiation Induced Pinning Centers
T. Baumgartner, M. Eisterer, H. W. Weber +3
We report non-Cu critical current densities of 4.09 * 10^9 A/m^2 at 12 T and 2.27 * 10^9 A/m^2 at 15 T obtained from transport measurements on a Ti-alloyed RRP Nb3Sn wire after irr…
