6 FAQs about [Preparation of superconducting container]

Can a superconducting sample be synthesised using ultrahigh vacuum?

However, the synthesis of superconducting samples has been proven to be challenging. Here, an ultrahigh vacuum (UHV) $ {\mathrm {\text {in situ}}}$ reduction method is developed using atomic hydrogen as a reducing agent and is applied in the lanthanum nickelate system.

How can superconductivity be achieved?

On an empirical basis, it seems natural to expect that superconductivity can be achieved through the synthesis of cuprate analogs that share common features including spin one-half, two-dimensionality, and strong antiferromagnetic correlations.

What is the reduction window for achieving superconducting transition?

The reduction parameters, including the reduction temperature (TR) and hydrogen pressure (PH), are systematically explored. It is found that the reduction window for achieving superconducting transition is quite wide, reaching nearly 80°C in TR and three orders of magnitude in PH when the reduction time is set to 30 min.

Can infinite-layer nickelates be used to synthesis a superconductor sample?

Learn more. Since their discovery, the infinite-layer nickelates have been regarded as an appealing system for gaining deeper insights into high-temperature superconductivity (HTSC). However, the synthesis of superconducting samples has been proven to be challenging.

Can superconducting ND 0.8 SR 0.2 Nio 2 films grow?

Which XRD pattern is a good criterion for superconducting films?

Nevertheless, we find that the XRD pattern of the precursor 113 phase is a good criterion to obtain superconducting films. The (002) peak of the secondary phase locates at about 47.8°, while for the 113 phase the (002) peak is at the 2 θ larger than 48° and thickness-dependent.
