The Meisner transition is the transition to a state where the Meisner effect is observed. The author also reports a "resistive transition", 1°C lower than the Meisner transition. He claims that this signs the superconductivity of the material and confirms the origin of the magnetic transition. > Is (Tl4Pb)Ba2MgCu8O13+ a ceramic compound? Most probably, yes.
