Magnetic structure of heavily Fermion TbxYb1-xAgGe

DOI

YbAgGe has an enhanced electronic specific heat coefficient and two magnetic phase transitions at TM1=0.8K and TM2=0.65K. We have grown a series of TbxYb1-xAgGe and YbAgGe polycrystalline samples and found Tb doping equivalent to magnetic field indeed supresses the antiferromagnetic system in YbAgGe towards spin-liquid or heavy fermion-liquid, which predicts a BCP or QCP possibly. we propose to measure the magnetic structure of the YbAgGe and Tb0.1Yb0.9AgGe. The results will help us to understand the evolution of exchange energies and the existence of BCP in YbAgGe under high magnetic field.
