Lorentz Microscopy

Lorentz microscopy is a powerful technique to investigate magnetic samples in and ex-situ. Studies can be made of specimens in their as-grown state, in remanent states, in the presence of applied fields or currents, and as a function of temperature.

From these can be derived basic micromagnetic information, the nature of domain walls, where nucleation occurs, the importance or otherwise of domain wall pinning, and many other related phenomena. In addition, the effects of materials processing (for example, patterning into small elements) on magnetic domain structure and magnetization reversal mechanisms can be analyzed.
