Collective states of interacting ferromagnetic nanoparticles

O. Petracic, X. Chen, S. Bedanta +4

Discontinuous magnetic multilayers [CoFe/Al2O3] are studied by use of magnetometry, susceptometry and numeric simulations. Soft ferromagnetic Co80Fe20 nanoparticles are embedded in…

Domain imaging, MOKE and magnetoresistance studies of CoFeB films for MRAM applications

J. M. Teixeira, R. F. A. Silva, J. Ventura +7

We present a detailed study on domain imaging, Kerr effect magnetometry (MOKE) and magnetoresistance (MR), for a series of 20 nm CoFeB thin films, both as-…

Electromigration in thin tunnel junctions with ferromagnetic/nonmagnetic: nanoconstrictions, local heating, and direct and wind forces

J. Ventura, J. B. Sousa, Y. Liu +2

Current Induced Resistance Switching (CIS) was recently observed in thin tunnel junctions with ferromagnetic (FM) electrodes \emph{i.e} FM/I/FM. This effect was attributed to elect…
