Most magnetic recording devices such as read heads and magnetic or magneto optical recording media have multilayer structures. In these devices, magnetic structural information on the interfaces is the key to achieve the high performance. Polarized neutron reflectometry is a unique and nondestructive tool to determine the magnetic interfacial structures. Recently the neutron reflectometer, SUIREN, was installed at the neutron guide hall in JRR-3 of Japan Atomic Energy Agency (JAEA). This reflectometer is capable of polarized neutron reflectometry, and is now open to users.
