Strictly In-Plane Vortex-like Excitations in Pseudogap Region of Underdoped $L{a}_{2-x}S{r}_{x}Cu{O}_4$ Single Crystals

H. H. Wen, Z. Y. Liu, Z. A. Xu +3

Nernst effect has been measured for an underdoped and an optimally doped $L{a}_{2-x}S{r}_{x}Cu{O}_4$ single crystal with the magnetic field applied along different directions. For both sam…
