Abstract

To experimentally clarify the changes in electronic structures of Gd₆₅Co₃₅ metallic glass by rejuvenation with temperature cycling (cryogenic rejuvenation), photoemission, inverse-photoemission, soft X-ray absorption, and emission spectroscopy (PES, IPES, SXAS, and SXES, respectively) experiments were carried out. By combining these techniques, element- and quantum number-selective partial density of states (pDOS) can be evaluated. By 40 repetitions of temperature changes between liquid N₂ and room temperatures, the Co 3d pDOSs are largely changed in magnitude. On the other hand, the Gd 4d and 4f pDOSs do not change beyond the range of experimental errors. These results are consistent with the structural changes by cryogenic rejuvenation found recently.

低温回春对Gd65Co35金属玻璃电子结构的影响

为了从实验上阐明Gd65Co35金属玻璃经过温度循环回火（低温回火）、光电、反光电、软x射线吸收和发射光谱（分别为PES、IPES、SXAS和SXES）实验后电子结构的变化。通过结合这些技术，可以评估元素和量子数选择偏态密度（pDOS）。通过在液体N2和室温之间进行40次重复的温度变化，Co 3d pDOSs的量级发生了很大变化。另一方面，Gd 4d和4f pdos在实验误差范围内没有变化。这些结果与近年来发现的低温回春引起的结构变化一致。

期刊介绍： Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
