[Pw_forum] why are there two Fermi energies?

[Eduardo Ariel Menendez Proupin]

I am sorry, Murphy's law has just acted. Find the figures here

Finally, I plotted Energy vs magnetization. Indeed, I have a minimum
at total magnetization equal 1. However, the
behavior is strange. The plot of E vs M is linear at each side of the

minimum, with a kink at M=1. Should'n it be rather like a parable ?
Please, see the plots here (above)
