Observation of Giant Band Splitting in Altermagnetic MnTe
T. Osumi, S. Souma, T. Aoyama +6
We performed angle-resolved photoemission spectroscopy (ARPES) on hexagonal MnTe, a candidate for an altermagnet with a high critical temperature (TN=307 K). By utilizing photon-en…
Unusual band evolution and persistence of topological surface states in high-T_C magnetic topological insulator
K. Hori, S. Souma, C. -W. Chuang +12
Understanding the mechanism of ferromagnetism in ferromagnetic topological insulators (TIs) is a key to realize exotic time-reversal-symmetry-broken quantum phases. However, electr…
Mössbauer studies of spin- and charge-modulations in BaFe2(As1-xPx)2
K. Komedera, J. Gatlik, A. Blachowski +4
The BaFe2(As1-xPx)2 compounds with x = 0 (parent), x = 0.10 (under-doped), x = 0.31, 0.33, 0.53 (superconductors with Tc = 27.3 K, 27.6 K, 13.9 K, respectively) and x = 0.70, 0.77…
Magnetic properties and magnetic structure of the frustrated quasi-one-dimensional antiferromagnet SrCuTeO
P. Saeaun, Y. Zhao, P. Piyawongwatthana +5
Magnetization measurements on single-crystal cubic SrCuTeO with an applied magnetic field of along three inequivalent high symmetry directions , , and …
Magnetic-field-induced topological phase transition in Fe-doped (Bi,Sb)Se heterostructures
Y. Satake, J. Shiogai, G. P. Mazur +9
Three-dimensional topological insulators (3D-TIs) possess a specific topological order of electronic bands, resulting in gapless surface states via bulk-edge correspondence. Exotic…
Ferroelectric atomic displacement in multiferroic tetragonal perovskite SrBaMnO
D. Okuyama, K. Yamauchi, H. Sakai +5
We investigate the crystal structure in multiferroic tetragonal perovskite SrBaMnO with high accuracy of the order of 10 Angstrom for an atomic displacem…
