<p> The data correction and the experimental procedures were upgraded in order to enhance the capability of the pulsed neutron diffractometers at the Materials and Life Science Experimental Facility (MLF) of the Japan Proton Accelerator Research Complex (J-PARC), and adopted for materials research. The magnetic structure of the intermetallic compound EuGa4 was investigated using the single-crystal pulsed neutron diffractometer SENJU. The diffraction spots from EuGa4 single crystal were clearly observed despite of extremely high neutron absorption of Eu. By adopting a wavelength-dependent absorption collection, the antiferromagnetic structure of EuGa4 with a nearly full magnetic moment of 6.4 μB of Eu was revealed. Further, the stroboscopic neutron diffraction system using the event data recording was developed for the engineering material diffractometer TAKUMI. The domain switching and the lattice strain induced by the intergranular stress in the piezoelectric material in the multilayer actuator under a cyclic electric field were observed with the nominal time resolution of 77 ms.</p>
