Magnetic properties of CrO₂ prepared by an ambient pressure TiO₂ support assisted synthesis

Abstract

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.
