1. A method comprising:
generating a first region of a pure magnetic field in a first processing zone using a microwave radiation source of the first processing zone, wherein the first processing zone is a single mode microwave radiation chamber;
generating a second region of a pure electric field in the first processing zone using the microwave radiation source, wherein the second region is spatially distinct from the first region;
loading, automatically, a first portion of an amorphous alloy into the first processing zone;
positioning the first portion in an annealing region, wherein the annealing region is a single field region selected from the first region and the second region;
heating the first portion in the annealing region;
applying a tension strain to the first portion while heating the first portion in the annealing region; and
unloading, automatically, the first portion from the first processing zone.
