Resonant x-ray emission spectroscopy (RXES) was employed at the U L-III absorption edge and the L-alpha 1 emission line to explore the 5f occupancy, n(f), and the degree of 5f -orbital delocalization in the hidden-order compound URu2Si2....
In search of novel, improved materials for magnetic data storage and spintronic devices, compounds that allow a tailoring of magnetic domain shapes and sizes are essential. Good candidates are materials with intrinsic anisotropies or...
Weyl fermions are a recently discovered ingredient for correlated states of electronic matter. A key difficulty has been that real materials also contain non-Weyl quasiparticles, and disentangling the experimental signatures has proven...
We report the synthesis, crystal structure, and characterization by means of single-crystal x-ray diffraction, neutron powder diffraction, and magnetic, thermal, and transport measurements of the new heavy-fermion compounds Ce2MAl7Ge4 (M...
We present studies of the magnetic domain structure of UMn2Ge2 single crystals using a home-built low temperature magnetic force microscope. The material has two distinct magnetic ordering temperatures, originating from the Mn and U...
We present results from point-contact spectroscopy of the antiferromagnetic heavy-fermion superconductor UPd2Al3: Conductance spectra are taken from single crystals with two major surface orientations as a function of temperature...
Unusual behavior in quantum materials commonly arises from their effective low-dimensional physics, reflecting the underlying anisotropy in the spin and charge degrees of freedom. Here we introduce the magnetotropic coefficient k =...
