摘要:
Described is an apparatus which comprises: a magnetic tunneling junction (MTJ) having a free magnetic layer; a piezoelectric layer; and a conducting strain transfer layer coupled to the free magnetic layer and the piezoelectric layer. Described is a method, which comprises: exciting a piezoelectric layer with a voltage driven capacitive stimulus; and writing to a MTJ coupled to the piezoelectric layer via a strain assist layer. Described is also an apparatus which comprises: a transistor; a conductive strain transfer layer coupled to the transistor; and a MTJ device having a free magnetic layer coupled to the conductive strain transfer layer.
摘要:
For providing a magnetostrictive film that can exhibit high magnetostrictive properties in the vicinity of zero magnetic field and their manufacturing methods, a magnetostrictive film thermal sprayed on an object under test includes a metallic glass film subjected to thermal processing at a temperature lower than the glass transition temperature and not lower than the Curie point, and shows a linearity between the magnetic field and the magnetostriction in at least a part of the magnetic field from -15 kA/m to +15 kA/m (both inclusive).
