Relation between the Exchange-Coupling Field and the Grain Size in Cr₇₀Al₃₀/Fe₁₉Ni₈₁ Bilayers

Effect of antiferromagnetic grain size on exchange-coupling field of Cr70Al30/Fe19Ni81 bilayers

“…% have a high electrical resistivity due to the narrow gap at the Fermi surface. 8 Cr with Si buffers were deposited on ͑100͒ Si substrates by a magnetron sputter deposition method. We have been investigating the exchange-coupling mechanism of Cr 70 Al 30 /Fe 19 Ni 81 bilayer films in terms of the crystal orientation, the interface roughness, and the grain size.…”

Bottom and top AF/FM interfaces of NiFe/FeMn/NiFe trilayers

“…We have also carried out a layer-by-layer investigation on the roughness properties of the interfaces of the Si/WTi/ NiFe/FeMn/WTi multilayer [21], where it was studied how successive layer depositions may change the roughness properties of the subsequent interfaces, and consequently the magnetism of the NiFe/FeMn exchanged-biased system deposited onto the Si/WTi substrate. It was also proposed a possible explanation for the discrepancy found in the literature [24][25][26][27][28] about the dependence of the EB effect on the rootmean-square roughness (s). This purpose was based on the Malozemoff model for the EB effect [22,23], considering other roughness properties, like the correlation length (j) and the fractal dimension (D) parameters [21].…”

Exchange-Coupling Field of MgO/Cr₇₀Al₃₀/Fe₁₉Ni₈₁ Films on (100) Si

“…Ocm at room temperature. Our previous experiments showed that the exchange-coupling field of C17oA)3iFel~i81 bilayers ranges about 100 Oe and that the antiferromagnetic grain size is responsible for detertnining the magnitude of the exchange-coupling field [7,8].…”
