Recent measurements of the out-of-plane magnetoresistance of delafossites (PdCoO$_2$ and PtCoO$_2$) observed oscillations which closely resemble the Aharanov-Bohm effect. We develop a semiclassical theory of these oscillations and show that they are a consequence of the quasi-2D dispersion of delafossites. We observe that the Lorentz force created by an in-plane magnetic field makes the out-of-plane motion of electrons oscillatory, similarly to Bloch oscillations. Analysis of the visibility of…

Layer-resolved many-electron interactions in delafossite PdCoO2 from standing-wave photoemission spectroscopy

When a three-dimensional material is constructed by stacking different two-dimensional layers into an ordered structure, new and unique physical properties can emerge. An example is the delafossite

    Quantum oscillations and high carrier mobility in the delafossite PdCoO(2).

    The low-temperature in-plane resistivity has an activated rather than the usual T(5) temperature dependence, suggesting a gapping of effective scattering that is consistent with phonon drag.

    Controlled Introduction of Defects to Delafossite Metals by Electron Irradiation

    The delafossite metals PdCoO$_{2}$, PtCoO$_{2}$ and PdCrO$_{2}$ are among the highest conductivity materials known, with low temperature mean free paths of tens of microns in the best as-grown single

    Magnetomorphic oscillations due to open orbits

    Abstract A simple two-dimensional model is used to show how open orbits may produce an oscillatory size effect in the transverse magnetoresistance of parallel-sided samples of very pure metals. Under

    New Oscillatory Magnetoresistance Effect in Gallium

    Magnetic size effects have increasingly become the subject of experimental and theoretical investigations1–8 because they provide a means of studying the Fermi surface, supplementing the information
