采用磁控溅射方法在Si(100)衬底上制备了由AlN和非晶态(Fe90Co10)(78)Si12B10层组成的两层薄膜磁电复合材料。经磁场处理后，它们在753 Hz机械共振时的ME系数为737V/cm Oe，在100 Hz时为3.1V/cm Oe。这是迄今为止报道的薄膜复合材料中最高的ME系数。此外，通过场退火产生的感生磁各向异性使得仅在一维上获得具有显著灵敏度的传感器元件成为可能，这使得实现三维矢量场传感器成为可能。(C)2010年美国物理研究所。[DOI：10.1063/1.3377908]
Thin film magnetoelectric (ME) two-two composites consisting of AlN and amorphous (Fe90Co10)(78)Si12B10 layers were fabricated by magnetron sputtering on Si (100) substrates. Upon magnetic field annealing they show an extremely high ME coefficient of 737 V/cm Oe at mechanical resonance at 753 Hz and 3.1 V/cm Oe out of resonance at 100 Hz. These are the highest reported ME coefficients in thin film composites ever. Furthermore, the induced magnetic anisotropy by field annealing serves the possibility to obtain a sensor element with a pronounced sensitivity in only one dimension, which allows the realization of a three-dimensional vector field sensor.
