[Mo(CN)
]
8HO (CuMo-film) was electrochemically synthesized. Unlike analogs with a formula of M[Mo(CN)]zHO (M = Mn, Fe, Co), which show tetragonal crystal structures, the CuMo-film shows a monoclinic structure in the C2/m space group with cell parameters of a = 17.2461 
= 125.1089
, and V = 1774.44 
. Extended X-ray absorption fine structure analysis traced the bond distances around the Cu site as 1.93-2.30 
for Cu-N and 2.01-2.40 for Cu-O. CuMo-film exhibits photo-switchable magnetization with T
= 18 K and dielectric relaxation related to the hydrogen bond network. The change of activation energy (E
) of the dielectric relaxation around 157 K (from E = 49.9 kJ mol
to E = 27.3 kJ mol on cooling) suggests that the development of the hydrogen bond network occurs below 157 K.

被引用回数：31 パーセンタイル：91.7(Instruments & Instrumentation)We studied the energy resolution of the pulsed neutron-beam of Accurate Neutron-Nucleus Reaction Measurement Instrument (ANNRI) at the Japan Proton Accelerator Research Complex/Materials and Life Science Experimental Facility (J-PARC/MLF). A simulation in the energy region from 0.7 meV to 1 MeV has been performed. Moreover, measurements have been done in the thermal and epithermal energies. The neutron energy resolution at ANNRI, which is determined by the time-of-flight technique, depends on the time structure of the neutron pulse. We obtained the neutron energy resolution as a function of the neutron energy by the simulation in the two operation modes of the neutron source: double and single bunch modes. In the double bunch mode, the resolution deteriorates above about 10 eV because the time structure of the neutron pulse splits into two peaks. The time structures at 13 energy points by measurements in the thermal energy region are in agreement with those of the simulation. In the epithermal energy region, the time structures at 17 energy points were obtained by measurements. The FWHM values of the time structures by the simulation and measurements are almost consistent. In the single bunch mode, the energy resolution is better than about 1% between 1 meV and 10 keV at the neutron source operation of 17.5 kW.
