Iron-site selective -Mössbauer spectra in external fields perpendicular to the layers were measured along the magnetization-hysteresis loop in a hcp-Tb/bcc-Fe multilayer with out-of-plane magnetic orientation and large coercivity. In the multidomain region, two oppositely and out-of-plane magnetized domain states in the Fe layers are distinguished in the spectra. The Fe-spin direction was found to be at oblique angles with respect to the surface normal (and Bext direction), reminiscent of a cone state. Fe-spin rotation was directly observed along the hysteresis loop, and the bcc-Fe-specific magnetization loop was calculated from the Mössbauer results.
