Single-crystal neutron diffraction shows collinear ferromagnetic order with uniform moment length on Nd sites in Nd3Ru4Al12, revising the prior unequal-moment ortho-FM model.
Dielectric spectroscopy on NdMgAl11O19 distinguishes crystal-field excitations (gap 25.85 K) from field-tuned antiferromagnetic correlations in the ground-state Kramers doublet below 30 K.

5d-mediated indirect exchange and effective spin Hamiltonians in Ce triangular-lattice delafossites
Indirect 5d-mediated exchange dominates in CsCeSe2, superexchange dominates in RbCeO2, and both contribute equally in KCeS2, with calculated spin Hamiltonians yielding magnetic excitation spectra in good agreement with experiment.
