Electronic structure of spin frustrated magnets: MnO spinel and postspinel
S. Hirai, Y. Goto, A. Wakatsuki +3
MnO is a spin frustrated magnet that adopts a tetragonally distorted spinel structure at ambient conditions and a CaMnO-type postspinel structure at high pressure.…
Giant atomic displacement induced by built-in strain in metastable MnO
Shigeto Hirai, Antonio M. dos Santos, Maxwell C. Shapiro +6
We present x-ray, neutron scattering and heat capacity data that reveal a coupled first-order magnetic and structural phase transition of the metastable mixed-valence post-spinel c…
Pressure-induced symmetry breaking in tetragonal CsAuI3
Shibing Wang, Shigeto Hirai, Maxwell C. Shapiro +4
Results of in situ high pressure x-ray powder diffraction on the mixed valence compound Cs2Au(I)Au(III)I6 (CsAuI3) are reported, for pressures up to 21 GPa in a diamond anvil cell…
