Query: Itinerant Ferromagnetism and Quantum Criticality in Sc$_3$In   The electronic structure and magnetic properties of hexagonal Sc$_3$In are
calculated within density functional theory. We find that the Fermi energy lies
in a region of flat Sc $d$ derived bands leading to a peak in the density of
states and Stoner ferromagnetism. The calculated local spin density and
generalized gradient approximation spin magnetizations are both enhanced with
respect to experiment, which is an indication of significant quantum critical
fluctuations, neglected in these approximations. We find, as expected, that the
ferromagnetism is initially enhanced under pressure, meaning that the critical
point cannot be reached with modest pressure. However, we find that the density
of states peak around the Fermi energy and the calculated density functional
magnetic properties are sensitive to the $c/a$ ratio, so that the quantum
critical point may be reached under uniaxial strain.
