Description

With plasma oxidisation to create an insulating layer of Al2O3, the authors have repeatedly fabricated Ni80Fe20/Al2O3/Co magnetic tunnel junctions which show obvious tunneling magnetoresistance (TMR) effect. At room temperature, the maximum TMR ratio reaches 6.0%. The switch field can be less than 800 A/m with a relative step width of about 2400 A/m. The junction resistance changes from hundreds of ohms to hundreds of kilo-ohms
