Magnetotransport Properties of Iron-Based Ladder Compounds BaFe2S3 and BaFe2Se3 under High Pressure
Takuya Aoyama, Kenya Ohgushi
The magnetotransport properties of the iron-based ladder compounds BaFe2S3 and BaFe2Se3 under various pressures were investigated. BaFe2S3 had a T^2 dependence in electrical resist…
Pressure-induced PT Symmetry Breaking in LaMnSi
Takuya Aoyama, Hikaru Taneoka, Takemi Yamada +2
We investigate the magnetotransport properties of the antiferromagnetic metal LaMnSi, in which the collinear magnetic order breaks both spatial inversion (P) and time-reversal (T)…
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…
Three-dimensional zigzag correlations in the van der Waals Kitaev magnet RuBr
H. Gretarsson, R. Iwazaki, F. Sato +8
Ruthenium trihalides Ru ( = Cl, Br, I) provide a tunable platform for Kitaev magnetism in two-dimensional van der Waals materials. Despite their similar crystal structures…
Piezomagnetic effect in 5 transition metal oxides YIrO and CdOsO with all-in/all-out magnetic order
Hiroki Nanjo, Yoshinori Imai, Takuya Aoyama +2
We investigated the piezomagnetic effect in pyrochlore-type oxides YIrO and CdOsO, which show a non-coplanar magnetic structure called the all-in/all-out an…
Ultrafast selective mid-infrared sublattice manipulation in the ferrimagnet
Davide Soranzio, Matteo Savoini, Fabian Graf +6
is a ferrimagnet with two oppositely ordered spin sublattices (Fe and Cr), connected via superexchange interaction, giving a non-zero net magnetic moment. We show, usin…
