Magnetic order induced by Fe substitution of Al site in the heavy fermion systems alpha-YbAlB4 and beta-YbAlB4
Kentaro Kuga, Gregory Morrison, LaRico Treadwell +2
beta-YbAlB4 is a heavy fermion superconductor that exhibits a quantum criticality without tuning at zero field and under ambient pressure. We have succeeded in substituting Fe for…
T/B scaling of magnetization in the mixed valent compound β-YbAlB4
Yosuke Matsumoto, S. Nakatsuji, K. Kuga +5
Here we provide the first clear evidence of Fermi-liquid breakdown in an intermediate valence system. We employ high precision magnetization measurements of the valence fluctuating…
Superconductivity in the Ferroquadrupolar State in the Quadrupolar Kondo Lattice PrTiAl
Akito Sakai, Kentaro Kuga, Satoru Nakatsuji
The cubic compound PrTiAl is a quadrupolar Kondo lattice system that exhibits quadrupolar ordering due to the non-Kramers ground doublet and has strong hybridizati…
Thermoelectric response near a quantum critical point of beta-YbAlB4 and YbRh2Si2: A comparative study
Y. Machida, K. Tomokuni, C. Ogura +7
The thermoelectric coefficients have been measured on the Yb-based heavy fermion compounds beta-YbAlB4 and YbRh2Si2 down to a very low temperature. We observe a striking difference…
