Abstract :
The gamma and neutron radiation tolerance of magnetic tunnel junctions with MgO barriers were investigated. The electrical transport and magnetic properties were measured in this effort. The characterization results show no statistically significant change in either tunneling magnetoresistance or coercivity from the radiation.
