  The unusual magnetic materials are significant in both science and
technology. However, because of the strongly correlated effects, it is
difficult to understand their novel properties from theoretical aspects.
Holographic duality offers a new approach to understanding such systems from
gravity side. This paper will give a brief review of our recent works on the
applications of holographic duality in understanding unusual magnetic
materials. Some quantitative compare between holographic results and
experimental data will be shown and some predictions from holographic duality
models will be discussed.
