spelling Electrical transport properties of CaB6Stankiewicz, JolantaSesé Monclús, JavierBalakrishnan, GeethaFisk, ZacharyUnder the terms of the Creative Commons Attribution License 3.0 (CC-BY).We report results from a systematic electron-transport study in a broad temperature range on 12 CaB6 single crystals. None of the crystals were intentionally doped. The different carrier densities observed presumably arise from slight variations in the Ca:B stoichiometry. In these crystals, the variation of the electrical resistivity and of the Hall effect with temperature can be consistently accounted for by the model we propose, in which B-antisite defects (B atom replacing Ca atom) are >amphoteric.> The magnetotransport measurements reveal that most of the samples we have studied are close to a metal-insulator transition at low temperatures. The magnetoresistance changes smoothly from negative - for weakly metallic samples - to positive values - for samples in a localized regime.We acknowledge support from Grant No. MAT2012-38213-C02-01, from the Ministerio de Economía y Competividad of Spain.
