Complex T-H phase diagram in Ce3TiSb5

We have carried out a detailed characterization of single crystals of the hexagonal compound Ce$_{3}$TiSb$_{5}$, via electrical resistivity, magnetization, and specific heat. These results are consistent with Kondo lattice behavior and an antiferromagnetic ordering temperature of 5.5 K. For magnetic fields applied along specific crystallographic orientations, metamagnetic transitions appear and are accompanied by a large negative magnetoresistance. As the temperature is progressively lowered, the metamagnetic transitions bifurcate.
