Verwey transition in Fe${}_3$O${}_4$ at high pressure: quantum critical behavior at the onset of metallization

J. Spałek, A. Kozłowski, Z. Tarnawski +5

We provide evidence for the existence of a {\em quantum critical point} at the metallization of magnetite Fe${}_3$O${}_4$ at an applied pressure of $p_c\approx 8$ GPa. We show t…
