@onlychigua 韩国科学家声称发现世界首个室温常压超导体 LK-99 该材料被命名为 LK-99，是一种参铜铅磷灰石，呈现六方晶体结构，超导临界温度最高 126.85°C (400K)。作者通过零电阻转变与迈斯纳效应的测量证实了该材料的超导性 (并附上了悬浮视频)。论文中详细介绍了材料的合成方法，条件与过程十分简单，因此很快就能被人验证。 https://arxiv.org/abs/2307.12037 #常温超导体

Magnetic measurement exhibits that significant diamagnetism appears at around 260 K and drops dramatically below 30 K implying coexistence of two superconducting phases. The upper critical magnetic field is larger than 1000 Oe at 250 K. Electric measurement manifests that the current-voltage curves deviate from the normal linear lineshape suggesting the presence of zero-resistance effect, and the critical current is around 50 μA at 140 K. These exotic magnetic and electric features strongly indicate these two components, variant apatite and covellite, individually trigger two superconducting phases at near-room and low temperatures. 通过在磷灰石框架中大量掺杂硫，我们合成了一种主要由变种磷灰石和靛铜矿（硫化铜）组成的新混合物。磁测量显示，在约260 K时出现显著的抗磁性，并在低于30 K时急剧下降，表明存在两个超导相共存。上临界磁场在250 K时大于1000 Oe。电测量表明，电流-电压曲线偏离正常的线性形态，暗示存在零电阻效应，并且在140 K时的临界电流约为50 μA。这些奇特的磁性和电性特征强烈表明，这两种成分，变种磷灰石和靛铜矿，在接近室温和低温下分别触发了两个超导相。 知乎讨论区 勘误：之前 GPT 翻译的时候把covellite 翻译成了黄铜矿，实际上是
