Spin-Orbital Ordering in Alkali Superoxides
Kohei Shibata, Makoto Naka, Harald O. Jeschke +1
Akali superoxides AO2 (A=Na, K, Rb, Cs), due to an open p shell of the oxygen ion O2^- with degenerate pi orbitals, have spin and orbital degrees of freedom. The complex magnetic,…
High-field phase diagram of the chiral-lattice antiferromagnet Sr(TiO)Cu4(PO4)4
Toshihiro Nomura, Yasuyuki Kato, Yukitoshi Motome +9
High-field phase diagram of a chiral-lattice antiferromagnet Sr(TiO)Cu4(PO4)4 is studied by means of the ultrasound, dielectric, and magnetocaloric-effect measurements. These exper…
Correlated Zak insulator in organic antiferromagnets
Takahiro Misawa, Makoto Naka
Searching for topological insulators in solids is one of the main issues of modern condensed matter physics since robust gapless edge or surface states of the topological insulator…
Unveiling new quantum phases in the Shastry-Sutherland compound SrCu2(BO3)2up to the saturation magnetic field
T. Nomura, P. Corboz, A. Miyata +8
Under magnetic fields, quantum magnets often undergo exotic phase transitions with various kinds of order. The discovery of a sequence of fractional magnetization plateaus in the S…
Anomalous Hall effect in antiferromagnetic perovskites
Makoto Naka, Yukitoshi Motome, Hitoshi Seo
We theoretically study the anomalous Hall effect (AHE) in perovskites with antiferromagnetic (AFM) orderings. By studying the multiorbital Hubbard model for electrons in perovs…
Cluster glass transition and relaxation in random spinel CoGa2O4
T. Naka, T. Nakane, S. Ishii +6
We report magnetic properties in the random spinel magnet CoGa2O4. Rietveld analysis of the x-ray diffraction profile for CoGa2O4 reveals that the Co and Ga ions are distributed ra…
