Magnetism and magnetic materials have been of scientific interest for over 1,000 years. More recently, fundamental investigations have focused on exploring the various types of magnetic materials and understanding the magnetic effects created by electric currents.

The properties of many devices are limited by the intrinsic properties of the materials that compose them.

我们的科学家团队拥有各种研究领域经验,包括生命科学、材料科学、化学合成、色谱、分析及许多其他领域.
