Front Cover: First-Principles Calculations and Optical Absorption Spectrum of a Light-Colored Aluminum-Substituted [epsi]-Iron Oxide Magnet

The cover picture shows the crystal structure, density of states, UV/Vis spectrum, and a photograph of a highly dispersed polymer solution of Al-substituted [epsi]-iron oxide. First-principles calculation implies that [epsi]-Al0.5Fe1.5O3 has a wide band gap, and the observed UV/Vis spectrum of the dispersed [epsi]-Al0.66Fe1.34O3 solution indicates a very light color. These results mean that Al-substitution lightens the color of [epsi]-iron oxide. Such a light-colored magnet is expected to find application as colored magnetic toner for color copy printing. Details are discussed in the Communication by S. Ohkoshi et al. on page 531 ff (DOI: 10.1002/ejic.201601169).
