Arrays of magnetic pillars 175 nm tall and 75 nm in diameter have been analyzed using Foucault mode Lorentz TEM. This paper describes a sample preparation route for TEM cross sections and shows that even in such small pillars sufficient magnetic contrast is visible to reveal the reversal of magnetisation in the pillars after application of a 2 kOe field. The reversal mechanism is shown to be incoherent by micromagnetic modelling.
