The former was related to mn doping, both of p - carries supplied by la3 + or oxygen hole and n - carries induced by changing mn4 + into mn3 + can be locally displaced and simultaneously response with external electric field., furthermore due to the overlaps between positive and negative carries. the latter was due to the phase transformation between orthorhombic and cubic, which was in fact the curie point
前者為la ~ （ 3 + ）和氧空位等產生的p型載流子和mn離子變價引入的n型載流子在外電場下發生局域重排產生的載流子極化，且由於正負載流子的迭加效應所致，該介電峰與mn離子的摻入相關；後者為體系出現相應的正交與立方結構的轉變所致，也即居里點。 -
