The Mössbauer effect in surface studies Fe57 on Ag
… them are described. M~ssbauer spectra of Fe57 on LiF, in Ag, and £n Ag have been obtained in the temperature range 100-400oK. The LiF experiment is assumed to be a:measurement of Fe on W which had contaminated the LiF. This experiment yielded a broad line which we interpret as a quadrupole …

The Mossbauer effect of FE57 on the surface of tungsten
The Mossbuaer effect of Fe 57 on the surface of polycrystalline tungsten has been measured over a temperature range of 80 - 5000 K, and at angles of 0° and 60° with respect to the normal. The M8ssbauer spectra consist of three unresolved lines, the middle one agreeing with measured spectra of Fe 57 …

High pressure Mössbauer studies of magnetic interactions in palladium-cobalt alloys
The pressure dependence of the Fe57 hyper fine field has been studied by means of the Mossbauer effect in a series of PdCo alloys consisting of 5, 8, 9, 12, and 15 atomic percent Co, up to 180 kilobarsat 297 oK. The Curie temperatures (Tc) of the 8% and 9% alloys are observed to increase with …

The Mossbauer effect in iron under very high pressure
The Mossbauer spectrum of Fe57 in iron metal has been measured at pressures up to 240 kilobars at room temperature. Below 133 kilobars the spectrum consists of the normal six lines characteristic of ferromagnetic, body-centered cubic iron. The internal magnetic field at the nucleus H decreases …
