Inelastic Neutron Scattering Studies of the Intermediate Valence Compound CePd3
V. R. Fanelli, J. M. Lawrence, C. H. Wang +5
Inelastic neutron scattering measurements on a CePd3 single crystal show a magnetic response at 300 K that is independent of momentum transfer with a Lorentzian quasielastic energy…
Low temperature behavior of the heavy Fermion Ce3Co4Sn13
A. D. Christianson, J. S. Gardner, H. J. Kang +4
The compound Ce3Co4Sn13 is an extremely heavy cubic heavy fermion system with a low temperature electronic specific heat of order ~4 J/mol-K2. If the compound is nonmagnetic, it wo…
Anisotropic intermediate valence in Yb2M3Ga9 (M = Rh, Ir)
A. D. Christianson, J. M. Lawrence, A. M. Lobos +10
The intermediate valence compounds Yb2M3Ga9 (M = Rh, Ir) exhibit an anisotropic magnetic susceptibility. We report measurements of the temperature dependence of the 4f occupation n…
Localized excitation in the hybridization gap in YbAl3
A. D. Christianson, J. M. Lawrence, E. A. Goremychkin +6
The intermediate valence compound YbAl3 exhibits a broad magnetic excitation with characteristic energy E1 ~ 50meV, of order of the Kondo energy (TK ~ 600-700K). In the low tempera…
Antiferromagnetism in Pr3In: Singlet/triplet physics with frustration
A. D. Christianson, J. M. Lawrence, J. L. Zarestky +7
We present neutron diffraction, magnetic susceptibility and specific heat data for a single-crystal sample of the cubic (Cu3Au structure) compound Pr3In. This compound is believed…
Crystalline Electric Field Effects in CeMIn5: Superconductivity and the Influence of Kondo Spin Fluctuations
A. D. Christianson, E. D. Bauer, J. M. Lawrence +9
We have measured the crystalline electric field (CEF) excitations of the CeMIn5 (M = Co, Rh, Ir) series of heavy fermion superconductors by means of inelastic neutron scattering. F…
