Exotic ground states in new geometrically frustrated oxides

挫折科学——一个系统无法以一种独特的方式找到最小化其能量的方法——在化学和物理领域带来了大量的新想法，从超导体的新路线，到多铁性等新的电子设备。这些化合物曾经只被认为具有理论意义，现在已经不仅仅是固态化学家和凝聚态理论家的玩具盒了——它们已经成为研究量子磁性的模型化合物。该提案概述了一种寻找新化合物的策略，这些化合物将测试描述固体磁性的现代想法，这些想法在日常生活中都有应用。如何创造基于磁现象的新设备)到异国情调(即。寻找固体中的磁单极子)。了解这些由三角形阵列上的磁自旋网络组成的新材料，对于理解一般的磁现象，以及为未来设计新技术至关重要。

The science of frustration - the inability of a system to find a way of minimizing its energy in a unique way - has brought about a plethora of new ideas in chemistry and physics, from new routes to superconductors, to new electric devices such as multiferroics. Once only thought to be of theoretical interest, these compounds have become more than a toy-box for solid state chemists and condensed matter theorists - they have become model compounds for studying quantum magnetism. This proposal outlines a strategy to search for new compounds which will test modern ideas for describing magnetism in solids, which has applications from the everyday (ie. how to create new devices based on magnetic phenomena) to the exotic (ie. searching for magnetic monopoles in solids). An understanding of these new materials, composed of networks of magnetic spins upon triangular arrays, is essential for understanding magnetic phenomena in general, and also for designing new technologies for the future.
