    • Magnetic entropy change of the layered perovskites La2-2xSr1+2xMn2O7 

      Wang, Aihua; Cao, Guohui; Liu, Yang; Long, Yi; Li, Yang; Feng, Zhaosheng; Ross, Joseph H. Jr. (AIP Publishing, 2005)
      Magnetocaloric properties of perovskite-type manganese oxides with double Mn-O layers of composition La2−2xSr1+2xMn2O7 (x=0.33 and 0.4) have been investigated. A broad peak of magnetic entropy change (−ΔSM) was observed ...
    • Superconductivity in gallium-substituted Ba8Si46 clathrates 

      Li, Yang; Zhang, Ruihong; Liu, Yang; Chen, Ning; Luo, Z. P.; Ma, Xingqiao; Cao, Guohui; Feng, Z. S.; Hu, Chia-Ren; Ross, Joseph H., Jr. (American Physical Society, 2007)
      We report a joint experimental and theoretical investigation of superconductivity in Ga-substituted type-I silicon clathrates. We prepared samples of the general formula Ba8Si46-xGax, with different values of x. We show ...
