The coercivity and form of iron deposited from the vapor were found to be influenced by the strength of a magnetic field applied during condensation. The intrinsic coercivities of powders deposited at -196°C and at -78°C in fields of 800 to 900 oersteds were about 120 oersteds. The greater fraction of particle diameters ranged from 10 to 20μ. No appreciable quantity of submicron particles was detected in several samples examined by electron microscopy. Line‐broadening in the diffraction patterns of the vapor‐deposited iron was attributed to strain, the magnitude of which was theoretically sufficient to account for the observed coercivities.
