Sažetak
Recent experiments have shown Co-doped La_0.5Sr_0.5TiO_3 (LSTO) as a diluted magnetic systems with a high T_c. La_0.5Sr_0.5TiO_3:Co (1.5%) layers were grown by PLD on SrTiO_3 (100) at O_2 pressures ranging from 6.10^(-7) to 2.3 10^(-4) mbar. All the films are epitaxial and ferromagnetic (T_c > 300 K). Upon decreasing the pressure, the out of plane cell parameter decreases and the electrical conductivity increases, while the magnetization shows a maximum (2.38 mu_B/Co) at p = 5.1 10^(-6) mbar. Experiments are being carried out to determine the origin of ferromagnetism and to measure the carriers' spin-polarization.
