摘要：

CrO2 has been prepared on polycrystalline rutile (TiO2) supports by thermal decomposition of impregnated Cr(NO3)(3) under ambient pressure conditions to give a material whose saturation magnetisation per Cr ion and coercivity at 5 K are found to be comparable to those for commercial CrO2 powder used in magnetic recording tape.
