Investigations of Ti-substituted CuFeO2 ceramics on the structure, defects, the local electron density and magnetic properties

Effect of Mn doping on the microstructure and magnetic properties of CuFeO2 ceramics

“…The magnetic properties of CFO ceramics improved by element doping was previously reported by Refs. [11,32,33]. The structure and area of the M-H loop are closely related to the material's particle size, composition, pore size, and cation distribution [34,35].…”

Unusual magnetic behavior of TiO2-doped CuFeO2 crystals (CuFe1−xTixO2) grown by the optical floating zone method

“…However, with further increase in Ti doping, the M – H curves (for the x = 0.01 and 0.015 crystals) became linear again, and thus returned to antiferromagnetic behavior. There are previous reports of doping with different ions altering the magnetic behavior of CuFeO 2 ceramics, 43,44 but these results are complicated due to appreciable contributions to the magnetic properties by the surface regions of the small component crystals. Both the composition and structure can influence the shape and size of M – H hysteresis loops, 45,46 and coupling between the electron spin, lattice and charge has been reported to regulate the magnetic properties of CuFeO 2 .…”
