Magnetic avalanches of minor fast-relaxing species of Mn12-acetate
摘要：
使用微米尺寸的温度计和霍尔酒吧，我们报告的时间分辨的局部温度和局部磁化强度的两种类型的磁雪崩（突然自旋反转）在分子magneti Mn 12-acetate，对应于雪崩的主要缓慢放松的结晶形式和雪崩的快速放松的次要物种，存在于所有生长的晶体这种材料。使用的实验协议，允许研究每种类型的雪崩，而不会触发雪崩的其他，和两种类型的雪崩同时进行。在磁性制备的样品，使这两种类型的雪崩，次要物种雪崩被发现作为催化剂的主要物种雪崩。磁性使这两种类型的雪崩，次要物种雪崩被发现作为主要物种雪崩的催化剂。
英文摘要：
Using micron-sized thermometers and Hall bars, we report time-resolved studies of the local temperature and local magnetization for two types of magnetic avalanches (abrupt spin reversals) in the molecular magneti Mn12-acetate, corresponding to avalanches of the main slow-relaxing crystalline form and avalanches of the fast-relaxing minor species that exists in all as-grown crystals of this material. An experimental protocol is used that allows the study of each type of avalanche without triggering avalanches in the other, and of both types of avalanches simultaneously. In samples prepared magnetically to enable both types of avalanches, minor species avalanches are found to act as a catalyst for the major species avalanches. magnetically to enable both types of avalanches, minor species avalanches are found to act as a catalyst for the major species avalanches.
