高温热处理控制相分离锰氧化物的热循环效应

Controlling thermal cycling effect in phase separated manganites with high temperature thermal treatments

Mariano Quintero, Bernardo Sievers, Joaquin Sacanell

摘要:

几种相分离的锰氧化物在每次经历以相分离为特征的范围内的相变时呈现出特殊的效果。该效应被称为热循环效应(TCE),其特征在于共存相的相对含量的单调变化。在这项工作中,我们分析了一种方法来控制TCE引起的影响,在高温下进行热处理。我们的研究结果揭示了一个复杂的相互作用的动态和静态特性的相分离状态,这可以分析在三个简单的参数。一个与静态属性相关,另一个与动态属性相关,最后一个充当两个特性之间的链接。

英文摘要:

Several phase separated manganites present a peculiar effect each time they go through a phase transition within the range characterized by phase separation. The effect is known as the thermal cycling effect(TCE) and is characterized by monotonous changes in the relative content of the coexisting phases. In this work, we analyze a way to control the effects induced by TCE, performing thermal treatments at high temperature. Our results revealed a complex interplay between the dynamic and static characteristics of the phase separated state, which can be analyzed in terms of three simple parameters. One related to the static properties, another to the dynamic properties and a last one that acts as a link between both features.
