Data for Unusual phase boundary of the magnetic-field-tuned valence transition in CeOs4Sb12
Listed in figshare
The phase diagram of the filled skutterudite has been mapped in fields H of up to and temperatures T down to using resistivity, magnetostriction, and MHz conductivity.
Description
The valence transition separating the semimetallic low-H, low-T L phase from the metallic high-H, high-T H phase exhibits a very unusual, wedge-shaped phase boundary, with a non-monotonic gradient alternating between positive and negative. The expected "elliptical" behavior of the phase boundary of a valence transition with H2∝T2 originates in the H and T dependence of the free energy of the f~multiplet.
Here, quantum oscillation measurements suggest that additional energy scales associated with a quantum critical point are responsible for the deviation of the phase boundary of from this text-book behavior at high H and low T. The distortion of the low-H, high-T portion of the phase boundary may be associated with the proximity of to a topological semimetal phase induced by uniaxial stress.<br><br>Figure2a.dat contains the data shown in Figure 2(a).
