説明
<p>The quasi-skutterudite superconductor La3Co4Sn13 with the Yb3Rh4Sn13-type cage-structure presents structural transition at T* = 152 K. As in the case with isostructural compound Sr3Rh4Sn13, it has been shown that T* can be suppressed to 0 K by applying external physical pressure in La3Co4Sn13. In order to investigate chemical pressure effect on La3Co4Sn13, we have synthesized single crystals of (La1−xAx)3Co4Sn13 (A = Sr, Ca) and measured magnetic susceptibilities and specific heats. From magnetic susceptibility and specific heat measurements, it has been suggested that T* can change sensitively to the composition.</p>
