Magnetic RAM To Preserve Data After Computer Shutdown
June 12, 2001 | Source: UniSci
A half-metallic ferromagnetic material may eventually allow us to create magnetic random access memory (MRAM), allowing for non-volatile computer memory systems.
The secret lies in harnessing spin polarization in a magnetic tunnel junction, using chromium dioxide (CrO2). The technique enables the material to retain magnetic orientation and thus preserve data.
