The neutron instruments suite, installed at the spallation neutron source of the Materials and Life Science Experimental Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC), is reviewed. MLF has 23 neutron beam ports and 21 instruments are in operation for user programs or are under commissioning. A unique and challenging instrumental suite in MLF has been realized via combination of a high-performance neutron source, optimized for neutron scattering, and unique instruments using cutting-edge technologies. All instruments are/will serve in world-leading investigations in a broad range of fields, from fundamental physics to industrial applications. In this review, overviews, characteristic features, and typical applications of the individual instruments are mentioned.

Single-crystal neutron diffraction study of the heavy-electron superconductor CeNiGe$$_{3}$$

Single-crystal neutron diffraction study was performed for anomalous antiferromagnetic ordering in a heavy-electron superconductor CeNiGe$$_{3}$$. We observed incommensurate magnetic Bragg reflections characterized with the propagation vector of $$k_{2}$$ = (0; 0:41; 1=2) below the N$'e$el temperature of 5 K, while there is no significant magnetic reflection at the commensurate propagation vector of $$k_{1}$$ = (1; 0; 0) at which another magnetic reflection was observed in the previous neutron diffraction study with a polycrystalline sample. From the single crystal study, we suggest that the magnetic phase of CeNiGe$$_{3}$$ at ambient pressure is characterized only by the incommensurate propagation vector $$k_{2}$$.

We have measured the specific heat and magnetization up to 50 T of polycrystalline samples of RCrTiO$$_{5}$$ (R=Pr, Nd, Eu, Sm and Gd) and also carried out powder neutron diffraction experiments of NdCrTiO$$_{5}$$ and Nd$$_{0.5}$$Pr$$_{0.5}$$CrTiO$$_{5}$$. From the analyses of specific heat data and magnetization curves up to 50 T of the systems, we have evaluated the magnetic interactions between the Cr$$^{3+}$$ - Cr$$^{3+}$$ magnetic moments and between the Cr$$^{3+}$$ -R$$^{3+}$$ ones. The temperature dependence of neutron magnetic reflection intensities of NdCrTiO$$_{5}$$ indicate that both the Cr$$^{3+}$$-moments and the Nd$$^{3+}$$-moments simultaneously order at $$T_mathrm{N}$$. Basis of the obtained magnetic behavior, the mechanism of magnetoelectric effect of RCrTiO$$_{5}$$ will be discussed.
