Previous work on the initial magnetization curve and major hysteresis loops suggested that applying either cyclic tension or compression to a sample of ferromagnetic material caused the magnetization to move irreversibly towards the anhysteretic curve. This explanation suggests that if the magnetization of the sample for a given field value is the same as that of a point along the anhysteretic curve, no irreversible change in magnetization should take place when an isofield cyclic uniaxial stress on the magnetization of a 2% Mn pipeline sample on small major hysteresis loops and minor hysteresis loops is presented here. The results show that the sense of the stress-induced irreversible changes in the unstressed magnetization is not always towards the anhysteretic. Examples where the change is away from the anhysteretic are shown, as well as cases where the cyclic uniaxial stress does not cause an irreversible change in the sample`s unstressed magnetization when that magnetization does not coincide with a point along the anhysteretic curve.
