heat treated grain 中文意思是什麼
heat treated grain
解釋
經熱處理的晶粒-
From the scanning electron microscope ( sem ) images, the higher the heat treatment temperature is, the larger the grain size is. the magnetization of samples treated at 1273k is larger than that of samples treated at 1073k ; 3. with the increasing of nife _ ( 2 ) o _ ( 4 ) contents, the resistivity of composite samples nd _ ( 0. 67 ) sr _ ( 0. 33 ) mno _ ( 3 ) / nife _ ( 2 ) o _ ( 4 ) is 1073k
值得注意的是,在這一溫區中,這種復合樣品的磁電阻是負的,即給樣品加磁場后,樣品的電阻率反而增大,與純nd067sro33mno3樣品的磁電阻性能恰好相反,其機制有待進一步研究; 4 .隨著s :含量的減小, ( ndl一srxmno3 ) 。
