Electronic specific heat and low energy quasiparticle excitations in superconducting state of $L{a}_{2-x}S{r}_{x}Cu{O}_4$ single crystals

Hai-Hu Wen, Zhi-Yong Liu, Fang Zhou +6

Low temperature specific heat has been measured and extensively analyzed on a series of $L{a}_{2-x}S{r}_{x}Cu{O}_4$ single crystals from underdoped to overdoped regime. From these data the…
