46_44b/2007Inside Cover: A Millimeter-Wave Absorber Based on Gallium-Substituted ε-Iron Oxide Nanomagnets (Angew. Chem. Int. Ed. 44/2007)

Millimeter waves , with a range of 30–300 GHz, are beginning to be used in electronic devices for high-speed wireless communications. In their Communication on page 8392 ff., S. Ohkoshi et al. report a new millimeter-wave absorber composed of ε-GaxFe2−xO3 (0.10≤x≤0.67) nanomagnets, which shows a ferromagnetic resonance in the 35–190-GHz region. The picture shows a Japanese landscape garden, Zuiho-in in Kyoto, in which the center rock, the ripples of sand, and the near rock evoke a millimeter-wave generator, millimeter waves, and the millimeter-wave absorber, respectively.
