Field-Tuning of the electron and hole populations in the ruthenate Bi_3Ru_3O_11

Wei-Li Lee, M. K. Hass, G. Lawes +3

Experiments on the Hall coefficient R_H and heat capactity C reveal an unusual, compensated electronic ground state in the ruthenate Bi_3Ru_3O_11. At low temperature T, R_H decreas…
