Bi is a semimetal with unique physical properties, including long charge carrier mean-free path (~1 micron at room temperature) [27], huge
magnetoresistance [24], or quantum confinement effects in nanostructures with dimensions of tens of nanometers [28].

The flexible MTJ devices yield significantly enhanced tunneling
magnetoresistance of [approximately equal to]300% and improved abruptness of switching, as residual strain in the MTJ structure is released during the transfer process.

The selections that make up the text cover the fundamentals of
magnetoresistance effects, spin current, spin hall effect and inverse spin hall effect, spin pumping, spin conversion at magnetic interfaces, and several other related subjects.
In theory, the larger the air-gap is, the greater the
magnetoresistance will be.
