Abstract

Abstract: Amorphous metal oxides (AMOs), characterized by long-range disorder and short-range order, exhibit distinct magnetic behaviors compared to crystalline materials. This review provides an overview of their structural characteristics, magnetism, and underlying mechanisms, with emphasis on typical phenomena such as superparamagnetism, spin glass, cluster glass and random exchange magnetic states, as well as their intrinsic correlations. Representative synthesis strategies, including melt-quenching, sol-gel, template, and mechanical amorphization, are also summarized. And their impacts on structure and properties are discussed. This review aims to elucidate the relationship between structural disorder and magnetism in AMOs.

Key words: Amorphous metal oxide, Local structure, Magnetism, Synthesis method
