Single-parameter scaling in the magnetoresistance of optimally doped La${}_{2-x}$Sr${}_x$CuO${}_4$

Christian Boyd, Philip W. Phillips

We show that the recent magnetoresistance data on thin-film La${}_{2-x}$Sr${}_x$CuO${}_4$ (LSCO) in strong magnetic fields ($B$) obeys a single-parameter scaling of the form MR$(B,T)=f…
