非晶态过渡金属超导体的Collver-Hammond曲线,到目前为止仍是一个未被充分解释的问题,获得这条曲线的实验工作是基于研究电子束蒸发薄膜的超导体临界温度而得到的。这些膜有很多是在冷底板上制取的,其中有些在室温下已全部晶化,同时,薄膜样品又给一些物理测量带来了困难,如比热测量,因此获得大块的非晶态过渡金属及其合金是研究非晶态过渡金属的很重要的内容。通常获得大块非晶态样品都采用超高速液相淬火的方法,用这种方法,已经制备出了几个在室温下稳定的非晶态过渡金属合金,亦称金属玻璃,对于金属Mo及其合金只有加入类金属,才有希望得到这种室温稳定的金属玻璃。在此之前,有人制备出了
The Collver-Hammond curve of amorphous transition metal superconductors has so far been a problem that has not been adequately explained. Experimental work to obtain this curve is based on a study of the critical temperature of superconductors in electron beam evaporated films. Many of these membranes are made on cold substrates, some of which are fully crystallized at room temperature, while the thin film samples in turn give rise to difficulties in some physical measurements such as specific heat measurements, thus obtaining bulk amorphous Transition metals and their alloys are very important for the study of amorphous transition metals. In general, bulk amorphous samples are obtained by ultra-high speed liquid-phase quenching. In this method, several amorphous transition metal alloys that are stable at room temperature have been prepared, also known as metallic glasses. For metallic Mo and Only by adding the metal alloy, only hope to get this stable metal glass at room temperature. Before that, someone prepared it
