So if we consider an ideal type II superconductor the magnetization should look like this
The Meissner state is to be found between $0$ and $H_{c1}$ and the superconductor works as an ideal diamagnet in this region. Between $H_{c1}$ and $H_{c2}$ is the mixed state where the vortices dominate the superconducting behaviour.
Now if we look at magnetization loops of real Type II superconductors then we see something like this

[Braz. J. Phys. vol.32 no.3 São Paulo Sept. 2002]
After the first loop we dont see here any ideal diamagnetic curve anymore (like the one represented as a straight line in the first picture).
But is the Meissner state still located in the region between $0$ and $H_{c1}$ or is it even existing in real Type II superconductors (how they are found in reality)?
