Spin-valve effects in point contacts to exchange biased Сo₄₀Fe₄₀B₂₀ films
Nonlinear current-voltage characteristics and magnetoresistance of point contacts between a normal metal (N) and films of amorphous ferromagnet (F) Сo₄₀Fe₄₀B₂₀ of different thickness, exchange-biased by antiferromagnetic Mn8₀Ir₂₀ are studied. A surface spin valve effect in the conductance of such...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Nonlinear current-voltage characteristics and magnetoresistance of point contacts between a normal metal (N)
and films of amorphous ferromagnet (F) Сo₄₀Fe₄₀B₂₀ of different thickness, exchange-biased by antiferromagnetic
Mn8₀Ir₂₀ are studied. A surface spin valve effect in the conductance of such F–N contacts is observed. The
effect of exchange bias is found to be inversely proportional to the Сo₄₀Fe₄₀B₂₀ film thickness. This behavior as
well as other magneto-transport effects we observe on single exchange-pinned ferromagnetic films are similar in
nature to those found in conventional three-layer spin-valves. |
