Methods of patterning a magnetic stack of a magnetic memory cell and structures thereof. In one embodiment, a folding partition includes one or more baffling devices. After a pyrophosphate salt containing Sn, Zr, Ti or Si is mixed with phosphoric acid, the mixture is maintained at a temperature of not less than 80\xb0 C. At least one securing flap is connected to one rhomboid edge, the rhomboid panels being foldable towards each other about the common fold line. Thereafter, the coded electronic copy is output as a physical document, and then imaged to create an electronic imaged copy. Additional modular head portions include circuitry connected with a connector in the head portion.
