Tunneling planer Hall (TPH) effect in Ni81Fe19/Al2O3/NixFe1-x trilayer junc
tion is different from general planer Hall effect in single-layer film or t
wo-layer junction. This effect concerns the spin-polarized transport,so tha
t the TPH voltage depends on the angle between magnetic vectors of two ferr
omagnetic layers. The TPH effect is reported to be influenced by compositio
n and magnetic properties of FM layers and the thickness of the insulating
layer.
