“…No doubt, manganese acquires magnetic moment. Moreover, contrary to some theoretical expectations and experimental results (see citations in [12]) dichroism of both elements looks much the same, which means that iron and manganese magnetic moments are parallel. No qualitative changes of the spectra were observed when the number of Mn monolayers was gradually increasing to 2, see Fig.…”

“…In ultrathin layers this volume may be regulated somehow by a substrate on which the film is grown. The cited experiments concern the layers of Mn grown on (001) bcc Fe [12] and (001) fcc Co [13]. Their magnetic properties shed some light on the magnetic Mn-Mn, Fe-Mn and Co-Mn interactions.…”

“…In the case of Mn grown on Fe the literature data, reviewed in [12], are highly confusing. The authors were thus very careful when growing the films (by MBE technique) and carrying out their detailed characterisations prior to making the experiment.…”

Neutrons and X-rays are well established tools for studying properties of condensed matter. With the advent of synchrotron radiation facilities their high photon fluxes started to be effectively used in the fields reserved earlier for neutrons. Although the two techniques are conceptually so similar that many physical problems can be solved usmg either technique, there are apparent fields in which one method is superior with respect to the other one. Therefore both techniques are often needed for characterization of the material of mterest. The paper concentrates on the studies of some static properties of metals and alloys. Relatively wide range of phenomena is presented, starting from structural aspects and ending on the sophisticated studies of the magnetic moment components. The paper is mtended to brmg a short (yet necessarily subjective and incomplete) review of what has recently been achieved by using neutrons and X-rays in metal (or more precisely -metallic states) studies.

“…Subsequent Xray photoelectron spectroscopy data [4], however, showed substantial magnetic moments on Mn atoms in the Mn/Fe(1 0 0) system. Magneto-optical Kerr effect (MOKE) measurements by Purcell et al [5] and X-ray magnetic circular dichroism (XMCD) by Andrieu et al [6,7] have concluded to a ferromagnetic coupling between Mn atoms and the Fe substrate.…”

“…14 Rather small magnetic moments compared to theoretical predictions are observed and the alignment between interfacial Mn and Fe moments is found to be parallel. 14,15 However, a number of questions still remain to be addressed. First of all, several recent calculations are devoted to the Mn/͑001͒ Fe system, leading to different lowest-energy spin configurations.…”

Growth, structure, and magnetic properties of thin Mn films epitaxially grown on (001) bcc Fe

et al. 1998

This work is dedicated to the study of structural and magnetic properties of Mn films epitaxially grown on ͑001͒ bcc Fe. At room temperature, the Mn growth mode on ͑001͒ Fe is observed to be layer by layer, without any interdiffusion, as shown by reflection high-energy electron-diffraction and Auger spectroscopy. Moreover, Mn is observed to segregate on top of the Fe surface. Two-dimensional pure Mn films are thus grown and the structural and magnetic properties of these Mn films are investigated by in situ and ex situ x-ray absorption ͑EXAFS͒ and magnetic circular dichroism. For uncapped Mn films, a structural and magnetic transition is observed between 2 and 3 Mn monolayers. Up to 2 Mn atomic planes, the EXAFS oscillations are consistent with calculated EXAFS spectra assuming a bct structure close to the Fe bcc structure. A ferromagnetic behavior is observed in these films. From 3 to 10 atomic planes, the Mn film structure changes and the ferromagnetic behavior disappears. Moreover, EXAFS analysis shows that this structural transition occurs at higher thicknesses for Fe capped Mn films. Nevertheless, the ferromagnetic behavior observed on 0-2-MLthick uncapped Mn films is no more stable in thick bct Mn films capped by Fe.
