Synthesis and Characterization of Hollow Magnetic Alloy (GdNi2, Co5Gd) Nanospheres Coated with Gd2O3

Synthesis and Characterization of Hollow Magnetic Alloy (GdNi2, Co5Gd) Nanospheres Coated with Gd2O3

Uniform magnetic hollow nanospheres (GdNi2, Co5Gd) coated with Gd2O3 have been successfully prepared on a large scale via a urea-based homogeneous precipitation method using silica (SiO2) spheres as sacrificed templates, followed by subsequent heat treatment. Nitrogen sorption measurements and scann...
