    Intertwined electronic and magnetic structure of the van-der-Waals antiferromagnet Fe2P2S6

    Many unusual and promising properties have been reported recently for the transition metal trichalcogenides of the type MPS3 (M = V, Mn, Fe, Ni ...), such as maintaining magnetic order to the atomically thin limi...

    Site-selective spectroscopy with depth resolution using resonant x-ray reflectometry

    Combining dissimilar transition metal oxides (TMOs) into artificial heterostructures enables to create electronic interface systems with new electronic properties that do not exist in bulk. A detailed understa...

    Nesting-driven multipolar order in CeB6 from photoemission tomography

    Some heavy fermion materials show so-called hidden-order phases which are invisible to many characterization techniques and whose microscopic origin remained controversial for decades. Among such hidden-order ...

    (π, π) electronic order in iron arsenide superconductors

    Electron density waves have been observed in many families of superconductors, and are often considered a prerequisite for superconductivity. Recent work on iron-arsenic (or iron pnictide) compounds revealed n...
