“…1 presents the x-ray diffraction (XRD) pattern at room temperature, which reveals the favorability of the (110) texture in the SIS single crystal. The temperature-dependent resistivity exhibits an anomalous resistivity transition around T * = 147 K and a superconducting phase transition at approximately 5 K. This finding is similar to that reported elsewhere and is understood as a CDW-like phase-induced structural transition and Fermi surface reconstruction at T * 16182025. The SIS compound is also known to crystallize into different crystal structures below and above the transition temperature, T * 161920.…”

“…The evolution of the order parameter of the modulation, the integrated intensity I , as a function of temperature can be fitted to a power law I (T) ~ [(T C - T) / T C ] 2β , with 2β~ 0.6 and T C ~ 146.1 K. The value of β is higher than the expected value for 3D systems32, and this deviation could be caused by thermal fluctuations. A thermodynamic study has also reported 3D fluctuation behavior for the phase transition that occurs in SIS and SRS compounds25. Similar results can be found in the literature on CDW systems2930.…”

X-ray scattering (XRS), x-ray absorption near-edge structure (XANES) and extended x-ray absorption fine structure (EXAFS) spectroscopic techniques were used to study the electronic and atomic structures of the high-quality Sr3Ir4Sn13 (SIS) single crystal below and above the transition temperature (T* ≈ 147 K). The evolution of a series of modulated satellite peaks below the transition temperature in the XRS experiment indicated the formation of a possible charge density wave (CDW) in the (110) plane. The EXAFS phase derivative analysis supports the CDW-like formation by revealing different bond distances [Sn1(2)-Sn2] below and above T* in the (110) plane. XANES spectra at the Ir L3-edge and Sn K-edge demonstrated an increase (decrease) in the unoccupied (occupied) density of Ir 5d-derived states and a nearly constant density of Sn 5p-derived states at temperatures T < T* in the (110) plane. These observations clearly suggest that the Ir 5d-derived states are closely related to the anomalous resistivity transition. Accordingly, a close relationship exists between local electronic and atomic structures and the CDW-like phase in the SIS single crystal.

Herein, the transport properties of Sr3Rh4Sn13, Ca3Rh4Sn13, and La3Rh4Sn13 quasi‐skutterudites are studied which show sharp superconducting (SC) transition with a transition temperature, Tc, ≈4.7, ≈8, and ≈2 K, respectively. In Sr3Rh4Sn13 system, electrical resistivity data evidence a pronounced anomaly before the SC transition at T* ≈136 K. No such anomalies are observed in the other two systems. Detailed structural investigations using synchrotron single‐crystal and powder diffraction reveal that these systems have cubic structure with Sr3Rh4Sn13 and Ca3Rh4Sn13 being in PmPmn space group setting. The La3Rh4Sn13 shows additional weak reflections which can be described by I4132 space group with almost doubled lattice parameters compared to Sr3Rh4Sn13 system. All three systems are found to show weak Raman modes below 240 cm−1. High‐pressure (HP) resistivity measurements up to 3.2‐GPa on Sr3Rh4Sn13 system reveal that the T* anomaly decreases almost linearly with pressure whereas the superconducting Tc almost linearly increases. HP structural investigations on Sr3Rh4Sn13 compound reveal that the structure remains in the cubic Pmn phase in 0–10 GPa range, following well a second‐order Birch–Murnaghan equation of state. The results provide interesting similarities and differences in the chemical and physical pressure effects on the quasi‐skutterudite X3Rh4Sn13 (x = Sr, Ca, and La) system.

We perform optical spectroscopy measurement on single-crystal samples of Sr 3 Rh 4 Sn 13 and (Sr 0.5 Ca 0.5 ) 3 Rh 4 Sn 13 . Formation of CDW energy gap was clearly observed for both single-crystal samples when they undergo the phase transitions. The existence of residual Drude components in σ 1 (ω) below T CDW indicates that the Fermi surface is only partially gapped in the CDW state. The obtained value of 2∆/K B T CDW is roughly 13 for both Sr 3 Rh 4 Sn 13 and (Sr 0.5 Ca 0.5 ) 3 Rh 4 Sn 13 compounds, which is considerably larger than the mean-field value based on the weak-coupling BCS theory. The measurements provide optical evidence for the strong coupling characteristics of the CDW phase transition.
