Published online: 1 September 2009

After a brief review of the basic methods of Lorentz transmission electron microscopy (LTEM), including the Transp ort-of-Intensity formalism for phase reconstruction, we present a few examples of the application of LTEM to multiferroic materials, in this case ferromagnetic shape memory alloys. We discuss observations of magnetic domain walls pinned to anti-phase boundaries in Ni2MnGa, and domain wall behavior under an in-situ applied magnetic field in Fe-Pd-Co.
