Perovskite Manipulated To Carry Both Electrical and Magnetic Polarization

Perovskite Manipulated To Carry Both Electrical and Magnetic Polarization

Researchers at the University of Liverpool in the UK have demonstrated the ability to manipulate a material so that it has both magnetic and electrical polarization , a feature that could lead to low-power electrical writing of information with non-destructive magnetic reading, and logic devices that can operate without charge current flow. A fair amount of research has gone into exploiting this property of both electrical and magnetic polarization in bismuth ferrite , which has the rare property of possessing a permanent local magnetic field while always possessing an electric polarization that can be switched by applying an electric field. However, in research published in the journal Science , the Liverpool team employed crystal chemistry to engineer specific atomic displacements in a layered perovskite to give it properties it did not previously possess. Perovskites ar...
