Structural modulation, physical properties, and electronic band structure of the kagome metal UCr $_{6}$ Ge $_{6}$

Z. W. Riedel, P. A. E. Murgatroyd, C. S. Kengle +13

The chemical flexibility of the $R M_{6} X_{6}$ stoichiometry, where an $f$ -block element is intercalated in the CoSn structure type, allows for the tuning of flatbands associated with k…

Putative excitonic insulating state in narrow-gap semiconductor La $_{3}$ Cd $_{2}$ As $_{6}$

Caitlin S. Kengle, Noah Schnitzer, Elizabeth A. Peterson +8

Excitonic insulators are electronically-driven phases of matter characterized by the spontaneous condensation of electron-hole pairs. Here we show that La $_{3}$ Cd $_{2}$ As $_{6}$ undergoes…

Pressure evolution of coplanar antiferromagnetism in heavy-fermion Ce $_{2}$ CoAl $_{7}$ Ge $_{4}$

M. O. Ajeesh, A. O. Scheie, Yu Liu +4

Ce $_{2}$ $M$ Al $_{7}$ Ge $_{4}$ ( $M =$ Co, Ir, Ni or Pd) are heavy-fermion materials and host a variety of ground states ranging from magnetism to non-Fermi liquid behavior. The Co, Ir,…

Magnetic order and physical properties of the Kagome metal UNb $_{6}$ Sn $_{6}$

Z. W. Riedel, W. Simeth, C. S. Kengle +8

The $R M_{6} X_{6}$ family of materials ( $R$ = rare-earth, $M$ = transition metal, $X$ = Ga, Si, Ge, Sn) produces an array of emergent phenomena, such as charge density waves, intrinsic…

UV $_{6}$ Sn $_{6}$ : a new kagome material with unusual $5 f$ magnetism

S. M. Thomas, C. S. Kengle, W. Simeth +15

Materials in the family $R$ V $_{6}$ Sn $_{6}$ ( $R =$ rare earth) provide a unique platform to investigate the interplay between local moments from $R$ layers and nonmagnetic vanadium k…

Mixed-valence state in the dilute-impurity regime of La-substituted SmB $_{6}$

Marta Zonno, Matteo Michiardi, Fabio Boschini +11

Homogeneous mixed-valence (MV) behaviour is one of the most intriguing phenomena of $f$ -electron systems. Despite extensive efforts, a fundamental aspect which remains unsettled is…

Colossal piezoresistance in narrow-gap Eu5In2Sb6

S. Ghosh, C. Lane, F. Ronning +5

Piezoresistance, the change of a material's electrical resistance ( $R$ ) in response to an applied mechanical stress ( $σ$ ), is the driving principle of electromechanical devices suc…
