| Abstract: | Layered borocarbides RB2C (R=Dy,Ho,and Er) have been studied by powder neutron diffraction
at 2–30 K. ErB2C has two-sublattice antiferromagnetic order below TN= 16:3 K, but DyB2C and
HoB2C show a coexistence of a conventional canted k = (000) ferromagnetic structure and unconventional
magnetic correlations. The k = (000) phase orders at Tc = 8:5 K (DyB2C) and 7.1 K (HoB2C),
but low-Q diffraction peaks from the unconventional correlations appear above Tc with different
critical temperatures for different peaks: at 8, 10.5, and 15.7 K for HoB2C. This scattering is fitted as
diffraction from a Warren-type random magnetic layer lattice and may result from quadrupolar
interactions between R3+ spins. |
