【摘要】 实验研究了温度和面内场共同作用下软畴段的行为.实验发现:面内场对软畴段的条泡转变场Hsb和软泡缩灭场H0有很大影响,而且Hsb和H0的变化与晶向有关.比较不同温度下、不同晶向上的结果,得到了与磁泡参量相关的分界面内场(Hip)d,不同温度下的软畴段对应着不同的(Hip)d,而且(Hip)d随着温度的升高而降低,在低温下,分界面内场(Hip)d是饱和磁化强度4πMs的2倍.更多还原

【Abstract】 The behavior of soft segments subjected to both temperature and in-plane field was experimentally studied. It was found that in-plane field Hip greatly affects the stripe-to-bubble transition field of soft domain segments Hsb and the collapse field of soft bubbles H0,and the changes of Hsb and H0 are related to the crystal orientation. Comparing the results for different crystal orientations and different temperatures,the authors obtained a dividing in-plane field (Hip)d related to the magnetic bubble parameters. The soft segments at different temperatures were responding to different (Hip)d. And the value of the dividing in-plane field decreased with increase of the temperature. (Hip)d is about two times of the saturated magnetization 4πMs at low temperatures.更多还原
