Magnetic tornado is stirring up the haze at Jupiter's poles
Magnetic tornado Magnetically Hydrocarbon
2024/12/11
Dark ovals in Jupiter's polar haze, visible only at UV wavelengths, were first noticed 25 years ago, then ignored. A new study shows that these dark UV ovals are common, appearing at the south pole in...

Dzyaloshinskii-Moriya（DM）相互作用，是一种反对称自旋交换作用，于上个世纪六十年代由I. Dzyaloshinskii利用唯象理论提出，并由T. Moriya在超交换相互作用中考虑自旋轨道耦合而发展的微观理论，被用来解释磁性体系中诸多新奇物理现象（自旋玻璃中的各向异性场、多铁性材料中的磁电耦合、自旋波的非对称色散关系、非共线磁结构等）。近十几年来，由于DM相互作用而实现的螺旋...
Lunar samples solve mystery of the moon's supposed magnetic shield

Tests of glass samples gathered on Apollo missions show magnetization may result from impacts of objects like meteors, not as a result of magnetization from the presence of a magnetic shield.
Superconductivity in a graphene system survives a strong magnetic field
graphene magnetic field MA TTG
2021/8/9
A material system known as magic-angle twisted trilayer graphene exhibits superconductivity. The observation that this superconductivity persists under a strong magnetic field could lead to advances i...
