Abstract

Researchers present flexible MgO barrier magnetic tunnel junction (MTJ) devices fabricated using a transfer printing process, which exhibit reliable and stable operation under substantial deformation of the device substrates. They CoFeB/MgO/CoFeB MTJs on conventional, thermally oxidized silicon substrates, release the MTJs from the substrates by etching away the underlying silicon, and transfer and adhere the MTJs onto fl exible polyethylene terephthalate (PET) substrates. The exible MgO barrier MTJs demonstrate improved performance on soft substrates by controlling the effect of strain on the devices.
