Reduction and reorientation of Cr magnetic moments in Fe/Cr multilayers observed by a119SnMössbauer probe

Thermal reaction and stability of NiFe/Cu thin films investigated by atom probe tomography

“…On the contrary, according to the Cu-Ni phase diagram, the Cu diffusion inside the Py grain boundaries is sufficient to transform these boundaries into paramagnetic spacers separating different grains of the Py layer. Thus, if the thickness of the new phase built around the grain boundary corresponds to the thickness of anti-ferromagnetic interlayer coupling, 24 we can have a frustration effect between the grains of the same layer and the adjacent Py layers, similar to the interfacial induced frustration in Fe-Cr 25 as shown in Fig. 6.…”

Effect of bidimensional Fe clusters on magnetic properties of Fe/Cr superlattices

“…In turn, Davies et al [5] detected experimentally an intermixing of the Cr and Fe atoms in the interlayer. Reduction and reorientation of the Cr magnetic moments in Fe/Cr multilayers were observed by Almokhtar et al [6] using a 119 Sn Mo¨ssbauer probe. The observations suggest that the magnetic frustration resulting from the Fe-Cr interface imperfections is accommodated by reduction or reorientation of the Cr magnetic moments for the samples depending on the growth temperatures.…”

Modifications of the spin density wave of Cr in Fe/Cr multilayers by insertion of Sn studied by neutron diffraction

“…The 119 Sn sites act as a probe where information is obtained from the local hyperfine field established by the surrounding magnetic Cr atoms. Using this approach, a reduction of the magnetic moment has been observed for thin Cr layers [8,10].…”
