 Abstract: We show that Ce- and Yb-based Kondo-lattice ferromagnets order mainly along the magnetically hard direction of the ground-state Kramers doublet determined by crystalline electric field. Here, we argue that this peculiar phenomenon, that was believed to be rare, is instead the standard case. Moreover, it seems to be independent on the Curie temperature TC, crystalline structure, size of the ordered moment, and type of ground-state wave function. On the other hand, all these systems show the Kondo coherence maximum in the temperature dependence of the resistivity just above TC, which indicates a Kondo temperature of a few degrees Kelvin. An important role of fluctuations is indicated by the non-mean-field-like transition in specific heat measurements as well as by the suppression of this effect by a strong Ising-like anisotropy. We discuss possible theoretical scenarios. © 2019 American Physical Society.
