Critical field of 2H-NbSe2 is determined for the field perpendicular to the conducting planes down to 50 mK, by magnetoresistance measurements. It is the first time that such a measurement is extended below 1 K. Variations are almost linear down to 1 K, with a little upward curvature, and...

Nature Commun:2H-NbSe2的多带电荷密度波 多频段电荷密度波作为一种非常重要的不稳定电子性,可能产生新颖的结构,目前人们对多能带超导现象进行广泛和深入的研究,但是人们通常忽略电荷密度波的多带电荷密度波(CDWs)。 有鉴于此,日内瓦大学Árpád Pásztor、Christoph Renner等报道能量分辨扫描隧道显微镜以简单的电荷累积...
We have made scanning tunnelling microscope (STM) studies of the lattice expansion and topography of cleaved crystals of 2H-NbSe2 which were intercalated in situ with silver ions entering along one edge of the samples. The measurements confirm the high surface mobility of silver seen in earlier ...
