A geometrically frustrated lattice provides an ideal platform to search for novel electromagnetic phenomena, since it is proven to yield exotic topological electronic states as well as novel magnetic ground states. This paper reports magnetotransport properties across the spin-ice-like magnetic order and liquid-gas-type magnetic transitions in the well-characterized pyrochlore semimetal PrIrO. Remarkable field and pressure dependence of the anomalous Hall conductivity points to the dramatic change of the Weyl point locations in momentum space. These findings open up a new direction for topological band engineering in hybrid quantum materials with relativistic conduction electrons and localized magnetic moments.

Heavily doped graphene near -filling has attracted intense interest due to the extended flat band which is shifted to the Fermi level with anticipated superconductivity and spin density wave.This work reports progress with the experimental observation of an extended flat band below the Fermi level by Li intercalation of bilayer graphene. Moreover, the Li-intercalated graphene shows interesting coexistence and codevelopment of an extended flat band, Kekulé order, and electron-phonon interaction, thereby providing opportunities for investigating their interplay and flat-band-related electronic instabilities.
