Quenched Fe moment in the collapsed tetragonal phase of Ca_(1-x)Pr_x Fe_2As_2
《Chinese Physics B》2013年第5期55-59,共5页马龙 吉高峰 代佳 Saha S R Drye T Paglione J 于伟强 
Project supported by the National Natural Science Foundation of China (Grant Nos. 11074304 and 11222433);the National Basic Research Program of China (Grant Nos. 2010CB923004 and 2011CBA00112);supported by AFOSR-Multidisciplinary University, ResearchInitiative (Grant No. FA9550-09-1-0603)
We report 7SAs NMR studies on single crystals of rare-earth doped iron pnictide superconductor Ca1-xPrxFe2As2. In both cases of x = 0.075, 0.15, a large increase of Vq upon cooling is consistent with the tetragonal-co...
