We studied the in-plane angular magnetoresistance (AMR), in the normal state, of underdoped superconducting ${\mathrm{Sr}}_{1--x}{\mathrm{La}}_{x}\mathrm{Cu}{\mathrm{O}}_{2}$, which has the simplest crystal structure among cuprates. The measurements

Recently it has been proposed that the long-range electronic order formed by trimerons in magnetite should be frustrated due to the great degeneracy of arrangements linking trimerons. This result has important consequences as charge ordering from the
