Orbital Ordering in the Charge Density Wave Phases of BaNi${}_2$(As${}_{1-x}$P${}_x$)${}_2$

Tom Lacmann, Robert Eder, Igor Vinograd +8

We use resonant X-ray scattering at the nickel L${}_{2,3}$ edges to investigate the interplay between orbital degrees of freedom and charge density waves (CDW) in the superconductor…
