Coexistence of Bulk Superconductivity and Charge Density Wave inCuxZrTe3

“…2 (d), suggesting the intermediate or strong phonon-electron coupling. Figures 3 (a,b) show field dependence of magnetization of Cu 0.05 ZrTe 3 measured at different temperatures for H ⊥ c and H c. For H c, the H c1 is obtained using the demagnetization correction [33]. The H c1 (T) shows almost linear rather than H c1 = H c1 (0)[1-(T/T c ) 2 ] temperature dependence for both field orientations (Fig.…”

Superconductivity and charge density wave formation in lithium-intercalated 2H−TaS2

“…The results of angle-resolved photoemission spectroscopy experiments demonstrate that these two orders (CDWs and SC) in the above TMDs may be cooperative phenomena rather than competitive [10,11]. By contrast, it is usually found that the increase of T c is accompanied by the disappearance of CDWs for intercalated 2H-TaS 2 [12][13][14]. The interplay between the superconducting and CDW states has also been investigated by high-pressure experiments on bulk 2H-TaS 2 [15,16].…”

Vortex motion in layered superconductors Cu0.03TaS2

“…Our former results show that it is a weak pinned superconductor with moderate anisotropy, 9 and that it has a complex vortex phase diagram when H c as HTCS. 10 In order to investigate the vortex motion in Cu 0.03 TaS 2 more thoroughly, we used a special electrodes arrangement (Fig.…”
