Принято считать наиболее перспективными материалы, в которых одновременно с изменением магнитного состояния происходит структурное изменение, или просто резкое изменение объема.
It is considered to be the most promising materials simultaneously with the magnetic state change occurs a structural change, or simply a sharp change in volume.
It is considered the most promising materials in which simultaneously with the change in the magnetic state of a structural change, or just a sharp change in volume.
considered to be the most promising materials in which the magnetic condition occurs simultaneously with the change of structural change, or just a change of volume.
