We report the optical and magneto-optical properties of K2V3O8, an S=1/2quasi-two-dimensional Heisenberg antiferromagnet. Local spin densityapproximation electronic structure calculations are used to assign the observedexcitations and analyze the field dependent features. Two large magneto-opticaleffects, centered at ~1.19 and 2.5 eV, are attributed to field-induced changesin the V 4+ d to d on-site excitations due to modification of the local crystalfield environment of the VO5 square pyramids with applied magnetic field. Takentogether, the evidence for a soft lattice, the presence of vibrational finestructure on the sharp 1.19 eV magneto-optical feature,and the fact that theseoptical excitations are due to transitions from a nearly pure spin polarized Vd state to hybridized states involving both V and O, suggest that themagneto-dielectric effect in K2V3O8 is driven by strong lattice coupling.Comment: Zipped file containing 8 pages, 12 figures, in press PR
