Abstract

We investigated the in-plane angular magnetoresistance (AMR) of T^\ensuremath'-phase La_2\ensuremath-xCe_xCuO₄ thin films (x=0.06--0.15) fabricated by a pulsed laser deposition technique. The in-plane AMR with H\ensuremath∥ab shows a twofold symmetry instead of the fourfold behavior found in other electron-doped cuprates such as Pr_2\ensuremath-xCe_xCuO₄ and Nd_2\ensuremath-xCe_xCuO₄. The twofold AMR disappears above a certain temperature, T_D. The T_D(x) is well above T_c(x) for x=0.06 (\ensuremath∼110 K), and decreases with increasing doping until it is no longer observed above T_c(x) at x=0.15. This twofold AMR below T_D(x) is suggested to originate from an antiferromagnetic or spin-density-wave order.
