The temperature dependence of tunnel magnetoresistance (TMR) is investigated between 30 K and 300 K for annealed junctions with the structure of Ta(5)/Cu(10)/Ta(5)/NiFe(2)/Cu(5) /IrMn(10)/CoFe(2.5)/Al2O3(1.5)/CoFe(2.5)/NiFe(t)/Ta(5), where t = 10 and 100 nm. For the junction (t = 100 nm) annealed at 270°C we were able to separate the spin-dependent and the spin-independent contributions to the temperature dependence of the TMR. For the junction with t = 10 nm annealed at 300°C the electron spin… CONTINUE READING
