High temperature conventional superconductivity in hydrogen-rich materials under high pressure has been reportedly found in twelve different compounds in recent years. However, the experimental evidence on which these claims are based has recently been called into question. Here we discuss the measurement of trapped magnetic flux, that should establish definitively that these materials are indeed high temperature superconductors. Its absence would confirm claims to the contrary.

高压下超导氢化物中的通量俘获

据报道，近年来在 12 种不同化合物中发现了高压下富氢材料的高温常规超导性。然而，这些主张所依据的实验证据最近受到了质疑。在这里，我们讨论了被困磁通量的测量，这应该确定这些材料确实是高温超导体。它的缺席将证实相反的主张。
