Abstract
The anisotropy constants of iron have been determined from torque measurements on a {100} single-crystal disk in fields up to 15 000 oersteds or higher and at temperatures of 77, 195, and 300°K. The values of at the three temperatures are (520±10)×, (505±10)×, and (480±10)× ergs/; the value of at all three temperatures is (0±50)× ergs/. The anisotropy decreases as the fourth power of the saturation magnetization over the temperature range studied.
