Lorentz's Electron Microscopy of Thin Films with Frustrated Magnetic Structure

Abstract:

The unique electrical and magnetic properties Fe₈₆Mn₁₃C alloy (Hadfield's steel) are due to special modulated structure. The alloy is widely used in mechanical engineering. Complex studies of the structure and properties of the alloy both in bulk samples and thin-films are suggested to describe the formation of a deformation martensite structure in Fe₈₆Mn₁₃C alloy in the form of self-assembled clusters. It is shown that combinations of anti-ferromagnetic austenite and ferrimagnetic martensite of deformation create unique electric and magnetic properties of Fe₈₆Mn₁₃C alloy both in bulk and in a thin-film state. We seek to explain the reason for the change of the sign of thermoelectric effect depending on temperature. Our task is to investigate thin Fe₈₆Mn₁₃C films as a possible solution to the problems of spintronics.
