Query: Crystal field potential and short-range order effects in inelastic
  neutron scattering, magnetization and heat capacity of the cage-glass
  compound HoB12   The strongly correlated system Ho11B12 with boron sublattice Jahn-Teller
instability and nanoscale electronic phase separation (dynamic charge stripes)
was studied in detail by inelastic neutron scattering (INS), magnetometry and
heat capacity measurements at temperatures in the range 3-300 K. From the
analysis of registered INS spectra, we determined parameters of the cubic
crystal field at holmium sites, B4=- 0.333 meV and B6= -2.003 meV (in Stevens
notations), with an unconventional large ratio B6/B4 pointing on the dominant
role of conduction electrons in the formation of a crystal field potential. The
molecular field in the antiferromagnetic state, Bloc = (1.75+- 0.1) T has been
directly determined from the INS spectra together with short-range order
effects detected in the paramagnetic state. A comparison of measured
magnetization in diluted Lu0.99Ho0.01B12 and concentrated HoB12 single crystals
showed a strong suppression of Ho magnetic moments by antiferromagnetic
exchange interactions in holmium dodecaboride. To account explicitly for the
short-range antiferromagnetic correlations, a self-consistent holmium dimer
model was developed that allowed us to reproduce successfully field and
temperature variations of the magnetization and heat capacity in the cage-glass
phase of HoB12 in external magnetic fields.
