Magnetic field tunability of spin-polarized excitations in a high-temperature magnet

We bring together magnetic circular dichroism, photoconductivity, and complementary first-principles calculations in order to unravel spin-charge interactions in the high Curie temperature magnet NiFe2O4. Analysis uncovers a massive set of well-isolated spin-down states, a metamagnetic transition in...
