Transport and magnetic properties of La1.48Nd0.4Sr0.12CuO4/La0.67Sr0.33MnO3 bilayer

We have grown La1.48Nd0.4Sr0.12CuO4/La0.67Sr0.33MnO3 (LNSCO/LSMO) bilayer structure on SrTiO3 (0 0 1) substrate. Both temperature dependences of resistivity and magnetization curves show anomalies between 60 < T < 80 K, where a low-temperature orthorhombic (LTO) to low-temperature tetragonal (LTT) structural transition is observed in LNSCO bulk crystal. It is suggested that the formation of domains in LSMO layer can relax the strains caused by the LTO–LTT transition in LNSCO layer.
