NixCoy-based thick-film magnetoresistors (TF-MRs) have been prepared with two different approaches: either the in situ alloy formation (and sintering) from fine powders of Ni and Co or the sintering of a Ni70Co30 powder obtained by co-reduction of Ni(II) and Co(II) acetates in diethyleneglycol. The pastes, printed on properly glazed alumina substrates in meander configuration, have been fired in N-2. The microstructure, electrical and magnetoresistive properties of these films have been studied. Both materials appear of interest for the implementation of contactless sensors.

Abstract
NixCoy-based thick-film magnetoresistors (TF-MRs) have been prepared with two different approaches: either the in situ alloy formation (and sintering) from fine powders of Ni and Co or the sintering of a Ni70Co30 powder obtained by co-reduction of Ni(II) and Co(II) acetates in diethyleneglycol. The pastes, printed on properly glazed alumina substrates in meander configuration, have been fired in N-2. The microstructure, electrical and magnetoresistive properties of these films have been studied. Both materials appear of interest for the implementation of contactless sensors.
