摘要: Mossbauer absorption spectra were measured for oriented samples of α- and β-FeOOH particles at antiferromagnetic paramagnetic states, which prepared utilizing the anisotropic particle shape. Considering intensity ratio six peaks, direction electron spin in state was concluded to be parallel crystal c -axis each compound. From quadrupole doublet, electric field gradient discussed. The axis estimated -plane.
