“…In order for this to be determined from dHvA measurements several harmonics of these frequencies would have to be measured. 15 We did not observe the harmonics in these measurements, and need to make measurements to higher fields at mK temperatures to do so.…”

The de Haas -van Alphen effect and energy band calculations are used to study angular dependent extremal areas and effective masses of the Fermi surface of the highly correlated antiferromagnetic material CeRhIn5. The agreement between experiment and theory is reasonable for the areas measured with the field applied along the (100) axis of the tetragonal structure, but disagree in size for the areas observed for the field applied along the (001) axis where the antiferromagnetic spin alignment is occurring. Detailed comparisons between experiment and theory are given.

“…Another member of the hexaboride family CeB 6 exhibiting non-superconducting heavy-fermion metallic behavior, has been intensely investigated in the past because of its intriguing low-temperature magnetic phases [18][19][20][21][22][23][24][25][26] as well as dense Kondo behavior [27][28][29]. CeB 6 exhibits antiferromagnetic (AFM) order below T N = 2.3 K [22], which is preceded by another phase transition at T Q = 3.2 K, whose order parameter has long remained hidden from standard experimental probes such as neutron diffraction [21,23].…”

Rare-earth hexaborides have attracted a considerable attention recently in connection to variety of correlated phenomena including heavy fermions, superconductivity and low temperature magnetic phases. Here, we present high-resolution angle-resolved photoemission spectroscopy studies of trivalent CeB 6 and divalent BaB 6 rare-earth hexaborides. We find that the Fermi surface electronic structure of CeB 6 consists of large oval-shaped pockets around the X points of the Brillouin zone, while the states around the zone center Γ point are strongly renormalized. Our first-principles calculations agree with our experimental results around the X points, but not around the Γ point, indicating areas of strong renormalization located near Γ. The Ce quasi-particle states participate in the formation of hotspots at the Fermi surface, while the incoherent f states hybridize and lead to the emergence of dispersive features absent in the non-f counterpart BaB 6 . Our results provide a new understanding of the electronic structure in rare-earth hexaborides, which will be useful in elucidating the nature of the exotic low-temperature phases in these materials.

“…[33]. While the determination of the effective g-factor in f -electron materials is often made complicated by the spin-dependence of m * and scattering rate [34][35][36], URu 2 Si 2 proves to be a simple exception − 16 spin zeroes are observed in the amplitude on rotating the field from the c-axis by an angle θ [19], enabling the θ-dependence of g * to be mapped to unprecedented detail [32].

Sequential Spin Polarization of the Fermi Surface Pockets inURu2Si2and Its Implications for the Hidden Order

Using Shubnikov-de Haas oscillations measured in URu2Si2 over a broad range in a magnetic field of 11-45 T, we find a cascade of field-induced Fermi surface changes within the hidden order phase I and further signatures of oscillations within field-induced phases III and V [previously discovered by Kim et al., [Phys. Rev. Lett. 91, 256401 (2003)]. A comparison of kinetic and Zeeman energies indicates a pocket-by-pocket polarization of the Fermi surface leading up to the destruction of the hidden order phase I at ≈35 T. The anisotropy of the Zeeman energy driving the transitions in URu2Si2 points to an itinerant hidden order parameter involving quasiparticles whose spin degrees of freedom depart significantly from those of free electrons.
