Abstract

The properties of IrMn spin valves with t _IrMn≤26Å are explored at temperatures down to 5 K. The structure is: Ti(50Å)/ NiFe(40Å)/Co(8Å)/Cu(30Å)/Co(30Å)/IrMn(tÅ)/ Ti(50Å) on a Si substrate. The low temperature giant magnetoresistance(GMR) is not greatly affected by the thickness of the IrMn. The thinner the IrMn, the lower the temperature at which the GMR is adversely affected. This is consistent with a reduction in blocking temperature. A number of interesting features in the coercivity and field training are IrMn thickness dependent.
