论文摘要
芒斯特大学实验团队的两篇最新文章由S.O.领导Demokritov在2006年首次发现的永久性抽水下展示了与Bose-Einstein凝结（BECM）有关的几个重要事实。它们与这种现象的现有理论相矛盾，这预测了镁质与重新对称性的强烈自发侵犯之间的有吸引力的相互作用。在本文中，我们表明，这些理论与镁的寿命相比，隐式假设所有放松过程都很快，而其中一种理论（两个能量的最小值之间的放松）很慢。我们对负责Minima松弛的过程进行了分类，并提出了他们的分析理论。我们分析了缓慢的微米间弛豫如何与镁冷凝物的铁磁铁的预期特性修饰。
Two recent articles of the Munster University experimental team led by S.O. Demokritov displayed several important facts related to the Bose-Einstein condensation of magnons (BECM) under permanent pumping first discovered in 2006. They contradicted existing theories of this phenomenon, which predict the attractive interaction between magnons and strong spontaneous violation of the reflection symmetry. In this article, we show that these theories implicitly assumed all relaxation processes to be fast compared with the lifetime of the magnons, whereas one of them -- relaxation between two minima of energy -- is slow. We classify processes responsible for the inter-minima relaxation and present their analytic theory. We analyze how the slow inter-minima relaxation modifies the anticipated properties of a ferromagnet with the magnon condensate.
