A neutron polarizing supermirror is one of the most important optical elements to polarize neutron beams. The polarizing supermirror needs to display high polarization efficiency over a wide bandwidth under low external field when it is used for a time-of-flight neutron scattering instrument at spallation neutron sources such as the J-PARC MLF. In this article, recent research results on the development of the polarizing supermirror with high-performance conducted to meet a variety of research demands at the MLF are presented.
