Abstract

The spin valves structures prepared were made by an anti-ferromagnetic layer composed by 50mass%Fe and 50mass%Mn and another layer composed by Fe and Ni in different mass proportions by Thermionic Vacuum Arc method. Mechanical tests were carried on deposited carbon film using a Fischerscope H100 DSI.depth sensing indentation tester, and scanning electron microscope (SEM) JEOL type with 1 nm resolution used after the nanoindentation print of different loads..
