Vortex pinning of BaKBiO investigated by magneto-optical Kerr-effect and magnetization measurements

Soichiro Yamane, Sota Nakamura, Atsutoshi Ikeda +8

Vortex pinning plays a crucial role in determining properties of type-II superconductors. For example, it governs the irreversible magnetic response as well as dissipation caused b…

Magneto-optical imaging of macroscopic altermagnetic domains in MnTe

Gakuto Watanabe, Soichiro Yamane, Ryotaro Maki +6

Altermagnets are a new class of magnets accompanying global time-reversal symmetry breaking (TRSB) without net magnetization. The TRSB results in formation of novel altermagnetic d…

Magneto-optical Kerr effect measurements under bipolar pulsed magnetic fields

Soichiro Yamane, Sota Nakamura, Atsutoshi Ikeda +3

The magneto-optical Kerr effect (MOKE) is a powerful probe of magnetism. Its contact-free optical nature makes it potentially well suitable for measurements under pulsed magnetic f…

Magneto-optical Kerr-effect measurements under pulsed magnetic fields over 40 T using a compact sample fixture

Atsutoshi Ikeda, Sota Nakamura, Soichiro Yamane +3

The magnetic field is one of the most fundamental control parameters in materials science. A pulsed magnetic-field apparatus can generate high magnetic fields that are inaccessible…

Born-limit scattering and pair-breaking crossover in d-wave superconductivity of (TMTSF)2ClO4

Shota Yano, Kazumi Fukushima, Katsuki Kinjo +8

In the quasi-one-dimensional organic unconventional superconductor (TMTSF)2ClO4, the randomness of the non-centrosymmetric ClO4 anions can be experimentally controlled by adjusting…
