The next generation of miniaturized devices will increasingly rely on "smart materials", materials with the uncanny ability to respond to an external stimulus by abruptly changing their properties in a reversible manner. Multiferroics, exhibiting at once, a magnetic and a ferroelectric ordering are potentially such smart materials. While the interplay between magnetic ordering and ferroelectricity in these compounds is presently one of the unanswered fundamental questions in condensed matter physics, the occurrence of both orders simultaneously is rare and very often occurs at low temperature. The recent emergence of thin films and nanostructures of materials with good multiferroic properties at room temperature has been a turning point opening the way for using multiferroics/magnetoelectrics into novel integrated devices, in areas such as sensing, energy conversion, as well as photonics and high-frequency electronics for telecommunication.

下一代小型设备将越来越依赖“智能材料”，具有不可思议的材料，能够通过以可逆的方式突然改变其性质来应对外部刺激。一次性表现出的多表象可能是这种智能材料。尽管这些化合物中磁性排序与铁电性之间的相互作用目前是凝结物理物理学中未解决的基本问题之一，但两种顺序同时出现的情况很少见，并且经常出现在低温下。在室温下，具有良好多用量特性的材料的薄膜和纳米结构的最新出现已成为一个转折点，为在感测，能量转换以及高光子和高光子和高光谱等领域中使用多种表情/磁性的途径为新颖的集成设备开辟了道路。 - 电信电子的频率电子设备。
