Autor: Ghimire, Sunil, Kończykowski, Marcin, Cho, Kyuil, Tanatar, Makariy A., Torsello, Daniele, Veshchunov, Ivan S., Tamegai, Tsuyoshi, Ghigo, Gianluca, Prozorov, Ruslan

Publikováno v: MDPI Materials 14, 3267 (2021)

Static (DC) and dynamic (AC, at 14 MHz and 8 GHz) magnetic susceptibilities of single crystals of a ferromagnetic superconductor, $\textrm{EuFe}_{2}(\textrm{As}_{1-x}\textrm{P}_{x})_{2}$ (x = 0.23), were measured in pristine state and after different

Effects of 6 MeV proton irradiation on the vortex ensemble in BaFe$_{2}$(As$_{0.67}$P$_{0.33}$)$_2$ revealed through magnetization measurements and real-space vortex imaging

Autor: Park, Akiyoshi, Veshchunov, Ivan, Mine, Akinori, Pyon, Sunseng, Tamegai, Tsuyoshi, Kitamura, Hisashi

The change in vortex ensemble in BaFe$_{2}$(As$_{0.67}$P$_{0.33}$)$_2$, an isovalently doped iron-based superconductor (IBS), is studied through global magnetization measurements and single vortex imaging before and after 6 MeV proton irradiation. Th

Large and significantly anisotropic critical current density induced by planar defects in CaKFe4As4 single crystals

Autor: Pyon, Sunseng, Takahashi, Ayumu, Veshchunov, Ivan, Tamegai, Tsuyoshi, Ishida, Shigeyuki, Iyo, Akira, Eisaki, Hiroshi, Imai, Motoharu, Abe, Hideki, Terashima, Taichi, Ichinose, Ataru

Publikováno v: Phys. Rev. B 99, 104506 (2019)

Three independent components of critical current density, one for the H//c axis and the other two for the H//ab plane, have been studied in CaKFe4As4 single crystals. When the magnetic field is applied along the c axis, we observed fish-tail-like pea

Mesoscopic Models of Plants Composed of Metallic Nanowires

Autor: Strukova, Galina K., Strukov, Gennady V., Postnova, Evgeniya Yu., Rusanov, Alexander Yu., Veshchunov, Ivan S.

Various metallic structures of complex shape resembling living plant organisms (biomimetics) are produced as a result of selfassembly of nanowires growing on porous membranes in the course of pulse current electrodeposition. These structures occur if

International audience; The interplay between superconductivity and magnetism is one of the oldest enigmas in physics. Usually, the strong exchange field of ferromagnet suppresses singlet superconductivity via the paramagnetic effect. In EuFe 2 (As 0
