ab-plane resistivity and possible charge stripe ordering in strongly underdoped La${}_{2-x}$Sr${}_x$CuO${}_4$ single crystals

R. S. Gonnelli, V. A. Stepanov, A. Morello +4

We have measured the ab-plane resistivity of La${}_{2-x}$Sr${}_x$CuO${}_4$ single crystals with small Sr content (x=0.052 $÷$ 0.075) between 4.2 and 300 K by using the AC Van der Pauw te…
