A plethora of temperature induced phase transitions have been observed in$[CH_3NH_3][M(HCOO)_3]$ compounds, where M is Co(II) or Ni(II). Among them, thenickel compound exhibits a combination of magnetic and nuclearincommensurabil-ity below N\'eel temperature. Despite the fact that thezero-field behavior has been previously addressed, here we study in depth themacroscopic magnetic behavior of this compound to unveil the origin of theatypical magnetic response found in it and in its parent family of formateperovskites. In particular, they show a puzzling magnetization reversal in thecurves measured starting from low temperatures, after cooling under zero field.The first atypical phenomena is the im-possibility of reaching zeromagnetization, even by nullifying the applied external field and evencompensating it for the influence earth's magnetic field. Relatively largemagnetic fields are needed to switch the magnetization from negative topositive values or vice versa, which is compatible with a soft-ferromagneticsystem. The atypical path found in its first magnetization curve and hysteresisloop at low temperatures is the most noticeable feature. The magnetizationcurve switches from more than 1200 Oe from the first magnetization loop to thesubsequent magnetization loops. A feature that cannot be explained using amodel based on unbalanced pair of domains. As a result, we decipher thisbehavior in light of the incommensurate structure of this material. We propose,in particular, that the applied magnetic field induces a mag-netic phasetransition from a magnetically incommensurate structure to a magneticallycommensurate structure.
