Field evolution of quantum critical and heavy Fermi-liquid components in the magnetization of the mixed valence compound beta-YbAlB4

Yosuke Matsumoto, K. Kuga, Y. Karaki +5

We present the high-precision magnetization data of the valence fluctuating heavy fermion superconductor $\beta$-YbAlB${}_4$ in a wide temperature range from 0.02 K to 320 K spanning fou…
