Juan L. Sepulveda,Lee J. Vandermarks is because their electrical and magnetic properties show a variety, depending on the constituent elements. Among them, MnSi has been studied most extensively and revealed to be a helical magnet whose Néel temperature T. is 29 K . According to the neutron diffraction experiments performed by ISH

The second of these approaches applied to molecules has been dealt with in the review by Wilson (1981). Therefore that ground will not be covered in this chapter. However, there has been much progress using the so-

trajectories can thus be obtained by applying the laws of geometric optical image projection. We then require a knowledge of only the positions of the principal planes of the electron lens and the corresponding focal lengths to describe the effect of the lens, rather than needing to have a complete
