Low-voltage, piezoelectric membrane is big advance for spintronics

University of Wisconsin-Madison researchers have developed an all-thin-film membrane composite of the relaxor-ferroelectric material lead magnesium niobate-lead titanate (PMN-PT) and ferromagnetic nickel that demonstrates an intrinsic coupling between voltage and spin.
