Utilizing the neutron magnetic scattering, one can investigate magnetic materials by looking at their magnetic nano structures. It is not exaggerated to state that nearly all the present microscopic knowledge of solid state magnetism has been obtained by neutron magnetic scattering experiments in the steady state neutron beam facilities at research reactors. In this review, we would like to introduce basics of the neutron magnetic scattering and demonstrate its strength by presenting some recent experiments on magnetic materials performed at the Research Reactor JRR-3 facility in the Nuclear Science Research Center, Tokai, Japan Atomic Energy Agency. The operation of the pulsed neutron source facility in the Materials and Life Science Facility of Japan Proton Accelerator Complex (J-PARC) will make the magnetic neutron scattering techniques even more common place, and the complementary use of both the steady state and pulsed neutron facilities in the near proximity will serve the broad users from academia and industries investigating magnetic materials.
