I Difference between Zero-Field Cooling and Field Cooling

  1. May 1, 2016 #1
    I am currently doing a experimental project work on superconductors. I am supposed to study properties of FeTeSe.
    I am having trouble understanding the difference between Zero-Field Cooling and Field Cooling. In both cases, I am measuring magnetization with varying temperature (from lower to higher) while a non-zero magnetic field is applied. Why does it make a difference whether I cool after applying field or apply field after the temperature has been lowered as required.

    FeTeSe is presumably a type-II superconductor, right?
    What does that mean in terms of how it reacts to an applied magnetic field?

    Hint: Look up some information about the formation of vortices in a textbook (see e.g. Tinkham's book)
