摘要: The spin polarization of secondary electrons from a Cr film on Fe(100), measured with scanning electron microscopy analysis, oscillates as function thickness period near two atomic layers, consistent incommensurate spin-density-wave antiferromagnetism in the Cr. position phase slip due to incommensurability varies reversibly by 14 layers over temperature range 310 550 K. surface magnetic moment persists well above Neel bulk
