摘要
A magnetic junction usable in a magnetic device and a method for providing the magnetic junction are described. A first portion of a magnetoresistive stack corresponding to the magnetic junction is provided. Providing this portion of the magnetoresistive stack includes providing at least one layer for a free layer of the magnetic junction. A second portion of the magnetoresistive stack is provided after the step of providing the first portion of the magnetoresistive stack. The magnetoresistive stack is patterned to provide the magnetic junction after the step of providing the second portion of the magnetoresistive stack. An ambient temperature for the magnetoresistive stack and the magnetic junction does not exceed a crystallization temperature of the free layer after the step of providing the free layer through the step of patterning the magnetoresistive stack. The magnetic junction is annealed at an anneal temperature not less than the crystallization temperature after the step of patterning the magnetoresistive stack.
