"non-volatile, magnets not aligned, tunneling less efficient higher resistance expressed as magnetoresistive ratio efficiency tunneling magnetoresistive device: higher is better... cobalt-manganese alloys face-centered cubic or hexagonal crystal structures thermodynamically stable phases, weak magnetism... adding minimal iron to metastable body-centered cubic cobalt-manganese alloy... magnetoresistance ratio 350% room temperature, >1000% at low temperature... sputtering method, heating process"
