Abstract
Coherent electronic waves The wave nature of conducting electrons in solids can be revealed through interference effects. In layered materials, these effects are most often seen in in-plane transport. By contrast, Putzke et al. studied electronic transport perpendicular to the conductive layers in the ultraclean delafossites PdCoO 2 and PtCoO 2 . When an in-plane magnetic field was applied, the electrical resistance exhibited periodic oscillations as a function of field magnitude. The findings can be explained through a model that requires that the electronic waves remain coherent over macroscopic distances. Science , this issue p. 1234
