  • magnetovolume effect in mn3cu1 xgexn related to the magnetic structure neutron powder Diffraction Measurements
    Physical Review B, 2008
    Co-Authors: Satoshi Iikubo, Katsuaki Kodama, K. Takenaka, S Shamoto
    Abstract:

    Magnetic structures in an antiperovskite system, ${\mathrm{Mn}}_{3}{\mathrm{Cu}}_{1\ensuremath{-}x}{\mathrm{Ge}}_{x}\mathrm{N}$, with a large magnetovolume effect above $x=0.15$ have been studied by neutron powder Diffraction Measurement. The present neutron study revealed that not only a cubic crystal structure but also a ${\ensuremath{\Gamma}}^{5g}$ antiferromagnetic spin structure are key ingredients of the large magnetovolume effect in this itinerant electron system. The large magnetovolume effect is possibly ascribed to the geometrical frustration originating from the corner-shared octahedra of the antiperovskite structure.

  • opening of a charge gap with v trimerization in bav 10 o 15
    Physical Review B, 2010
    Co-Authors: Tomomasa Kajita, Toshiharu Suzuki, Takuro Katsufuji, T Kanzaki, Jungeun Kim, Kenichi Kato, Masaki Takata
    Abstract:

    A structural phase transition at ${T}_{c}\ensuremath{\sim}130\text{ }\text{K}$ in ${\text{BaV}}_{10}{\text{O}}_{15}$ containing modified ${\text{V}}^{3+}$ $(3{d}^{2})$ triangular lattices was studied. It was found that the electrical resistivity jumps by three orders of magnitude and a gap opens up in the optical conductivity spectrum at ${T}_{c}$. It was also found from synchrotron x-ray powder-Diffraction Measurement that the trimerization of the V ions occurs below ${T}_{c}$. These results indicate that the orbital ordering of $\text{V}\text{ }{t}_{2g}$ states occurs at ${T}_{c}$ and that induces a charge gap near the Fermi level in the electronic states of ${\text{BaV}}_{10}{\text{O}}_{15}$.

  • orbital ordering and magnetic field effect in mnv2o4
    Physical Review Letters, 2007
    Co-Authors: Toshiharu Suzuki, M Katsumura, Kouji Taniguchi, T Arima, Takuro Katsufuji
    Abstract:

    We studied the structural properties of an orbital-spin-coupled spinel oxide, MnV{sub 2}O{sub 4}, mainly by single-crystal x-ray Diffraction Measurement. It was found that a structural phase transition from cubic to tetragonal and ferrimagnetic ordering occur at the same temperature (T{sub s},T{sub N}=57 K). The structural phase transition was induced also by magnetic field above T{sub s}. In addition, magnetic-field-induced alignment of tetragonal domains results in large magnetostriction below T{sub s}. We also found that the structural phase transition is caused by the antiferro-type ordering of the V t{sub 2g} orbitals.
