• There are many methods to investigate domains , such as polarization microscopy , scanning electron microscopy , transmission electron microscopy , scanning electron acoustic microscopy and so on . however , these methods suffer from some serious disadvantages involving complex sample preparation , damage to sample , low resolution
  现有的铁电畴检测手段，如偏光显微镜、粉末花样技术、扫描电镜、透射电镜、扫描电子声显微镜等存在这样或那样的缺点：诸如制样繁琐、易破坏原始畴结构、或畴结构成像分辨率还不够高等。
