Sažetak
Charge stripe order is recognized as an important ingredient of the physics of cuprates, yet the thermodynamics of its formation and the influence of disorder are unclear. We present a study of the development of charge stripes in the cuprate La1.8xEu0.2SrxCuO4 using three complementary experimental techniques: nuclear quadrupole resonance, nonlinear conductivity and specific heat. We find an intermediate phase between(pseudogapped) metal and charge stripes, existing in a dome-shaped region of the phase diagram and appearing through a sharp phase transition. A novel technique is used for measurements of nonlinear response, which show that the new phase is consistent with a charge nematic. This is in agreement with recent predictions of charge stripe formation with quenched disorder. Our experiments thus resolve the intricate process of charge stripe formation and provide a link to other materials with electronic nematic order.
