• In nickel・manganese alloy with stoichiometric composition Ni_3Mn, very remarkable magnetic after-effect has been found. The after-effect (i) is large at the intermediate state of order of the alloy, (ii) is most noticeable at the steepest part of the magnetization curve, (iii) is comparatively temperature insensitive, and (iv) is not affected by mechanical deformation. The experimental formula of the phenomenon is well expressed by an analytical form derived by Street and Woolley on the basis of the concept of thermal activation process of single domain particles. It has been confirmed by electron microscopic study that the alloy with remarkable magnetic after-effect is composed of innumerable number of small particles of prolate ellipsoidal form embedded in matrix. The dimension of these particles is of such a order of magnitude that is occupied by only single magnetic domain.
