Abstract

<p>We study the unconventional quantum critical behavior observed in the Yb-based quasicrystal and its approximant crystal. We show that (i) both the quasicrystal and approximant crystal have the same critical exponent and (ii) the divergent phenomenon in the magnetic susceptibility is also observed under pressure with the same critical exponent in the quasicrystal, whereas the approximant exhibits quantum critical behavior only at the critical pressure. We discuss the possible origin of the unconventional quantum criticality.</p>
