Abstract
An analysis of the effect of stress on spike or closure domains formed at pores is presented in an effort to gain further insight into the effects of applied stress on remanence ratios. The model is based on the concept that spike domain volume is dependent on the domain wall energy, which in turn is influenced by magnetic anisotropy and stress energies. The results indicate that the effects on remanence ratios are proportional to 
, the ratio of the product of porosity and average magnetostriction constant to the magnitude of the first-order magnetocrystalline anisotropy constant. This conclusion is used in conjunction with the results of previous models to offer an explanation of the effects of applied stress in the Y3 Mnx Fe5-x O12 system.
