Abstract

Field-induced magnetization jumps with similar characteristics are observed at low temperature for the intermetallic germanide Gd₅Ge₄ and the mixed-valent manganite Pr_0.6Ca_0.4Mn_0.96Ga_0.04O₃. We report that the field location---and even the existence---of these jumps depends critically on the magnetic field sweep rate used to record the data. It is proposed that, for both compounds, the martensitic character of their antiferromagnetic-to-ferromagnetic transitions is at the origin of the magnetization steps.
