The authors are grateful to Professors K. Ishida and K. Oikawa, Tohoku University, for useful discussions on ferromagnetic SMAs. They also thank Drs. Y. Kondo and I. Ishikawa, JEOL Ltd., for their support of the development of the double probe piezodriving holder. This study was supported by a Grant-in-Aid from the Ministry of Education, Culture, Sports, Science and Technology of Japan.

N2 - This article reports our recent studies on the magnetic imaging by electron holography or Lorentz microscopy, which is combined with other supplementary techniques related to transmission electron microscopy (TEM). By combining with dark-field imaging, the "one-to-one correspondence" between the magnetic domain walls and antiphase boundaries (APBs) in a ferromagnetic shape memory alloy (SMA) Ni2Mn(Al,Ga) was revealed. In order to examine both magnetism and conductivity in a nanoscale area, we have developed a double probe piezodriving holder, by which microprobes can be brought in contact with the portion of interest. The conductivity measurement can be simultaneously performed with Lorentz microscopy or electron holography.
