    Hi

    Does nonlinear conductive liquid metal exist? Which and where?

    thx

    Thermal or electrical conductivity?

    Do you mean a material whose conductance changes as a function of a parameter (like temperature)?

    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.
