Thermodynamic and transport properties of high-quality single crystals of the altermagnet CrSb
Shubhankar Paul, Atsutoshi Ikeda, Giordano Mattoni +2
Altermagnetism (AM) is an emerging magnetic order unifying essential characteristics of ferromagnetic and antiferromagnetic states. The CrSb has attracted significant interest owin…
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…
Fermi-liquid behavior and characteristic temperature-dependent susceptibility in clean RuO crystal
Shubhankar Paul, Atsutoshi Ikeda, Hisakazu Matsuki +6
The magnetic nature of the altermagnet candidate RuO remains under debate. It has been recently shown from quantum oscillations and angle-resolved photoemission spectroscopy (A…
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…
