    • A magnetic tunneling junction (MTJ) in an MRAM array is disclosed with a composite free layer having a FL1/FL2/FL3 configuration where FL1 and FL2 are crystalline magnetic layers and FL3 is an amorphous NiFeX layer for improved bit switching performance. FL1 layer is CoFe which affords a high magnetoresistive (MR) ratio when forming an interface with a MgO tunnel barrier. FL2 is Fe to improve switching performance. NiFeX thickness where X is Hf is preferably between 20 to 40 Angstroms to substantially reduce bit line switching current and number of shorted bits. Annealing at 330° C. to 360° C. provides a high MR ratio of 190%. Furthermore, low Hc and Hk are simultaneously achieved with improved bit switching performance and fewer shorts without compromising other MTJ properties such as MR ratio. As a result of high MR ratio and lower bit-to-bit resistance variation, higher reading margin is realized.

    • Reading margin is improved in a MTJ designed for MRAM applications by employing a pinned layer with an AP2/Ru/AP1 configuration wherein the AP1 layer is a CoFeB/CoFe composite and by forming a MgO tunnel barrier adjacent to the CoFe AP1 layer by a sequence that involves depositing and oxidizing a first Mg layer with a radical oxidation (ROX) process, depositing and oxidizing a second Mg layer with a ROX method, and depositing a third Mg layer on the oxidized second Mg layer. The third Mg layer becomes oxidized during a subsequent anneal. MTJ performance may be further improved by selecting a composite free layer having a Fe/NiFeHf or CoFe/Fe/NiFeHf configuration where the NiFeHf layer adjoins a capping layer in a bottom spin valve configuration. As a result, read margin is optimized simultaneously with improved MR ratio, a reduction in bit line switching current, and a lower number of shorted bits.
