## Description

- description: Visualizing spin-polarized electronic states aids in designing and
    developing new materials and devices. Spin-resolved photoemission spectroscopy
    provides information on the spin-polarized electronic states. To investigate the
    spin-polarized electronic states in microscopic materials and devices, spin-resolved
    photoemission spectroscopy requires spatial resolution in a sub-micrometer scale.
    Here we show the imaging-type spin-resolved photoemission microscopy (iSPEM) with
    an ultraviolet laser developed at the National Institutes for Materials Science
    (NIMS). Our iSPEM achieves a spatial resolution of 420 nm, drastically improving
    by more than an order of magnitude compared to conventional spin-resolved photoemission
    spectroscopy instruments. Besides, the multi-channel spin detector significantly
    reduces the data acquisition time by four orders of magnitude compared to the
    conventional instruments. The iSPEM machine elucidates the spin-polarized electronic
    states of sub-micrometer scale materials, polycrystals, device structure samples,
    and so on, which have yet to be the target of conventional spin-resolved photoemission
    spectroscopy.
