Abstract:

A series of Ni2+ doped indium oxide nanocubes with different Ni2+ contents (nominally from 3 at.% to 20 at.%) were prepared by direct solvothermal method. We found that the highest Ni2+ doped percentage was 20 at.% in the experiment and crystalline sizes of these Ni2+ doped indium oxide specimens linearly increased with increments of doped contents and then decreased. Meanwhile, their magnetisms were also transferred from ferromagnetism to paramagnetic properties due to the stronger Ni–O–Ni paramagnetic chemical bonds. HRTEM, SAED and XRD further confirmed their magnetic properties were intrinsic and not caused by second impure phases.
