YSZ Flexible ceramic magnetic bilayers for remote sensing in extreme conditions

Flexible YSZ ceramic sheets were evaluated as potential platforms for flexible spintronic devices. These were coated with (Ni80Fe20, Py) films of increasing thicknesses ranging from 10nm -100nm by means of DC magnetron sputtering. The stability and the integrity of the Py film was evaluated as a function of temperature cycles and induced stress/ strain between 1000C and -25C. Characterization techniques included FE-SEM, profilometry, and Kerr microscopy. Work presented will provide the framework for next generation remote sensing devices for extreme conditions.
