Abstract
Magnetic structures in magnetic artificial lattices and chiral magnetic orders in chiral magnets have been quantitatively analyzed in the reciprocal space by means of small-angle electron scattering (SAES) method. Lorentz deflection due to magnetic moments and Bragg diffraction due to periodicity are simultaneously recorded at an angle of the order of or less than 1 × 10(-6) rad, using a camera length of more than 100 m. The present SAES method, together with TEM real-space imaging methods such as in-situ Lorentz microscopy, is very powerful in analyzing magnetic fine structures in magnetic materials. Indeed, the existence of both a chiral helimagnetic structure and a chiral magnetic soliton lattice in a chiral magnet CrNb3S6 has been successfully verified for the first time using the present complementary methods.
