In strongly correlated materials, quasiparticle excitations can carry fractional quantum numbers. An intriguing possibility is the formation of fractionalized, charge-neutral fermions, e.g., spinons and fermionic excitons, that result in neutral Ferm

Crystals of the KBaR(BO3)2 (R = Y, Gd, Tb, Dy, Ho, Tm, Yb and Lu) rare earth borates were grown by spontaneous nucleation from a KF-B2O3 flux. The crystals obtained were typically well-developed hexagonal plates about 1 mm in large dimension. The cry
