Finitistic dimensions of formal power series rings
Xiaolei Zhang, Weiheng Xia
We consider the big finitistic projective and flat dimensions of a commutative ring and of its formal power series ring. When the ring is Noetherian, both invariants increase by on…
EuIn2Sb2: epitaxially stabilized axion insulator candidate with strong spin-orbit coupling
Hsiang Lee, Shinichi Nishihaya, Markus Kriener +5
Eu triangular lattice layer compounds described by the general formula EuA2X2 have attracted growing attention due to a wide range of layered crystal structures and corresponding m…
Magneto-cubic and magneto-linear dependence observed in an in-plane anomalous Hall magnet
Ayano Nakamura, Shinichi Nishihaya, Mitsuru Akaki +9
The Hall effect, particularly that arising from in-plane magnetic field, has recently emerged as a sensitive probe of quantum geometric properties in solids. Especially in trigonal…
Stark difference in the in-plane anomalous Hall response in Zintl compounds EuA2Sb2 (A = Zn, Cd) thin films
Hsiang Lee, Shinichi Nishihaya, Markus Kriener +5
Recent observation of the in-plane anomalous Hall effect in magnetic Weyl semimetal EuCd2Sb2 has drawn attention to out-of-plane orbital magnetization induced by an in-plane field…
Anomalous Hall effect in Dirac semimetal probed by in-plane magnetic field
Shinichi Nishihaya, Hiroaki Ishizuka, Yuki Deguchi +5
Intrinsic anomalous Hall effect (AHE) formulated by geometric properties of Bloch wavefunctions is a ubiquitous transport phenomenon not limited to magnetic systems but also allowe…
Distinct topological Hall responses in CeCu-type EuZn and EuCd films
Yuto Watanabe, Shinichi Nishihaya, Markus Kriener +2
Rare earth intermetallic compounds crystallized in AlB-type and its low-symmetry derivative CeCu-type structures potentially host diverse frustrated magnetic structures and…
Topological Hall effect enhanced at magnetic transition fields in a frustrated magnet EuCd
S. Nishihaya, Y. Watanabe, M. Kriener +2
Emergent magnetic fields exerted by topological spin textures of magnets lead to an additional Hall response of itinerant carriers called the topological Hall effect (THE). While T…
Observation of in-plane anomalous Hall effect associated with orbital magnetization
Ayano Nakamura, Shinichi Nishihaya, Hiroaki Ishizuka +3
For over a century, the Hall effect, a transverse effect under out-of-plane magnetic field or magnetization, has been a cornerstone for magnetotransport studies and applications. M…
Magnetic structure of EuCdSb single-crystal thin-film
Eliot Heinrich, Ayano Nakamura, Shinichi Nishihaya +5
We investigate the magnetic order in single crystalline EuCdSb thin films using a combined theoretical and experimental approach. Resonant elastic x-ray scattering experime…
Berry curvature derived negative magnetoconductivity observed in type-II magnetic Weyl semimetal films
Ayano Nakamura, Shinichi Nishihaya, Hiroaki Ishizuka +5
Here we study nonmonotonic features which appear both in magnetoresistivity and anomalous Hall resistivity during the simple magnetization process, by systematically measuring type…
Intrinsic insulating transport characteristics in low-carrier density EuCd2As2 films
Shinichi Nishihaya, Ayano Nakamura, Mizuki Ohno +4
Searching for an ideal magnetic Weyl semimetal hosting only a single pair of Weyl points has been a focal point for systematic clarification of its unique magnetotransport derived…
