It<br />is found out that magnetic moments of TiO\(_2\) interface layers are around 0.18 \(\mu_B\) while they are mostly negligible in the pure LaAlO\(_3\)/SrTiO\(_3\) system. Even though magnetic moments are mainly produced by Ti t2g orbitals, oxygen plays a key role in the formation of the ferromagnetic state since polar distortions primarily occur in oxygen positions of the SrTiO\(_3\) and PbTiO\(_3\) sides in opposite directions.}, number={3}, journal={Communications in Physics}, author={Giang, Bach Huong and Trang, Nguyen Thuy and Nam, Tran Van and Cong, Bach Thanh}, year={2015}, month={Nov.}, pages={219} }
