We find anomalously large diamagnetic responses in the cage compounds AV2Al20 where A = Y and La, not A = Al0.3, Sc0.4, and Lu, despite the apparent similarities in crystal and electronic structures among these compounds. The magnetic susceptibilities of the Y and La compounds become -1.94 and -7.44 x 10-4 cm3 mol-1 at 10 K, respectively, the latter of which corresponds to approximately one-quarter of that of bismuth, a well-known diamagnetic material, in terms of unit volume. The origin is not…

Effect of the electropositive elements A = Sc, La, and Ce on the microscopic dynamics of AV2Al20.
TLDR
It is shown that the unusual anharmonicity of the Sc-dominated modes is due to the local potential of Sc featured by a strong quartic term, and the effect of the strong phonon renormalization in ScV2Al20 on thermodynamic observables is computed on grounds of the LDC derived inelastic response.

Interband contributions from the magnetic field on Hall effects for dirac electrons in bismuth.
TLDR
It is shown that there is an unconventional contribution to sigma_{xy} generated by the interband effects of a magnetic field, which is remarkable near the band edges and does not depend on impurity scatterings so much, suggesting the same origin as the known large diamagnetism.
