Does nonlinear conductive liquid metal exist? Which and where?
Thermal or electrical conductivity?
Do you mean a material whose conductance changes as a function of a parameter (like temperature)?
yes. as a function of time. i.e. the relaxation time of 1-10ms or something like that.
I was reading this but it is over my head.
As a function of time? Can't help there.
I was going to point out that metal conductors are subject to "skin effect" at higher frequencies, where the current restricts itself to an outer region, causing R to show an increase at some range of f. I surmise that in a molten metal it would behave similarly; could investigate using Hg.
There's nothing dealing with metal there. It's the plastic insulation they investigated.
Maybe if a metal or "liquid metal" is doped with the purpose of achieving a certain relaxation time! i.e. Alloy of some sort.
