Influence of ferromagnetic layer thickness on the magnetic properties of Cr/Fe1-xCox bilayers

Résumé

The influence of Fe1-xCox thickness on the magnetic properties of Cr/Fe1-xCox bilayers is investigated. Electronic structure calculations showed that the Cr moments are suppressed by Co addition and by the deposition of multiple Fe1-xCox layers. Cr/Fe65Co35 bilayers were studied experimentally. Structural investigations showed the presence of strain and a rough Cr/Fe65Co35 interface in the measured samples. The magnetic data was analyzed using the Mauri-Siegmann model, which showed that the interfacial Cr moments decrease with increasing Fe65Co35 thickness. A large bias field of 0.09T was found at 4K for the sample with a 10 nm thick Fe65Co35 layer, around 10 times larger than previous reports.
