目前对锰氧化物的研究

The current spin on manganites

C. Israel, M. J. Calderón, N. D. Mathur

摘要:

在材料中,具有非常不同的磁性和电子性质的相的存在和共存既不寻常又令人惊讶。锰氧化物特别吸引人的想象力,因为它们表现出的复杂性掩盖了它们的化学单相性质。这种复杂性的出现是因为磁性,电子和晶体结构相互作用,以提供共存的奇异磁性和电子相。这种共存是自组织的,但容易受到外部扰动的影响,允许我们在这里描述的那种微妙而富有想象力的实验。此外,这些实验表明,每个竞争阶段本身仍然是一个未完全解决的谜。

英文摘要:

In a material, the existence and coexistence of phases with very different magnetic and electronic properties is both unusual and surprising. Manganites in particular capture the imagination because they demonstrate a complexity that belies their chemically single-phase nature. This complexity arises because the magnetic, electronic and crystal structures interact with one another to deliver exotic magnetic and electronic phases that coexist. This coexistence is self-organized and yet readily susceptible to external perturbations, permitting subtle and imaginative experiments of the type that we describe here. Moreover, these experiments reveal that each competing phase itself remains an incompletely solved mystery.
