The ever-increasing demand for faster, smaller and non-volatile electronics is pushing the limits of present semiconductor-based information processing and storage systems. Ferromagnetic layers in contact with an anti-ferromagnet exhibit an interfacial magnetic coupling termed as exchange bias coupling. Theoretical calculations have predicted the possibility of significant changes in the interfacial magnetization and spin polarization in a ferromagnet in response to the ferroelectric polarization state across the interface. Ferromagnetism and spin polarization can be controlled and manipulated through a coupling of a magnetic layer to a ferroelectric or a multiferroic.}, year = {2010}, journal = {Nature Materials}, volume = {9}, number = {5}, pages = {380-381}, publisher = {Nature Publishing Group}, issn = {14761122}, doi = {10.1038/nmat2762}, note = {cited By 43}, language = {eng}, }
