Internal magnetic fields in hcp-iron

Abstract
The magnetic behavior of hcp-Fe (epsilon iron) has been investigated by the Mössbauer Effect over a wide range of temperature T, pressure P, and applied magnetic field H0. The internal field Hi of the induced moment is given by Hi=0.20±0.01 H0 and is independent of T and P. Enhanced paramagnetism is suggested as the most likely origin for a contribution of this magnitude to Hi.
