de Haas–van Alphen effect and Fermi surface properties in rare earth and actinide compounds
Fermi surface properties in rare earth (R) and actinide (An) compounds of RX3 (X: Al, Ga, In, Si, Ge, Sn, Pb), AnX₃ , RTIn₅ (T: transition metal), and AnTGa5 are clarified as a function of the number of valence electrons. The electronic state can be changed by applying pressure and magnetic field....

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Fermi surface properties in rare earth (R) and actinide (An) compounds of RX3 (X: Al, Ga, In, Si, Ge, Sn,
Pb), AnX₃ , RTIn₅ (T: transition metal), and AnTGa5 are clarified as a function of the number of valence electrons.
The electronic state can be changed by applying pressure and magnetic field. A change of Fermi surface
properties associated with the metamagnetic behavior and the quantum critical point is also clarified precisely,
together with the split Fermi surfaces in the non-centrosymmetric crystal structure, and the de Haas–van Alphen
oscillations in the superconducting mixed state. In the quantum critical point region, the conduction electrons, or
quasi-particles, are of an f-electron character, with heavy effective masses of 10–100m₀ (m₀ is the rest mass of
an electron) and condense into the unconventional (anisotropic) superconducting state. |
