Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
42 words
A high conductivity, low migration rate metallic alloy for use in magnetic bubble domain structures comprising a host material of silver, and a dopant comprising 1% to 6% (atomic) and taken from the class comprising In, Mn, Bi, Cr, Pb, Cu, Be.
Claim 2
Dependent Claim
42 words
A high conductivity, low migration rate metallic alloy for use in magnetic bubble domain structures comprising a host material of silver, and a dopant comprising 1% to 6% (atomic) and taken from the class comprising In, Mn, Bi, Cr, Pb, Cu, Be.
Claim 3
Dependent Claim
24 words
The alloy recited in claim 1 wherein the upper limit of said dopant percentage approaches 25% but the conductivity of the alloy is diminished.
