C values (220–300 K) is obtained
by electrochemical reduction of aqueous solutions containing V3+ , Cr3+ ,
and [CrIII (CN)6 ]3− at -1.20 V vs. SCE. The samples are characterized by
VIS/near-IR spectroscopy, powder XRD, and magnetic measurements. The
colors range from colorless (x = 0) via green (x = 0.23) and dark green
(x = 0.35) to blue (x = 1). The new colored magnetic films could open up new
possibilities in the field of optomagnetic devices. — (MIZUNO, MIKIHISA;
