Fermi surface properties of low-concentration CexLa1-xB6: de Haas-van Alphen

摘要

The de Haas-van Alphen (dHvA) effect is used to study angular-dependent extremal areas of the Fermi surfaces and effective masses of CexLa1-xB6 alloys for x between 0 and 0.05. The dHvA signals from these alloys are observed to change from that arising from the normal two-spin metal, LaB6, to a single-spin sheet signal at x = 0.05. [References: 34]
