Elastic Neutron Diffraction Studies of Polycrystalline Co-doped CeCu2Ge2

DOI

A systematic study of physical properties on Ce(Cu1-xCox)2Ge2 reveals that the AFM ground state of CeCu2Ge2 can be continuously suppressed by Co doping and NFL type of behavior is seen around the critical concentration xc = 0.6. A significant deviation of physical properties from a FL behavior such as C/T proportional to T ^(-1+lambda) are observed around xc = 0.6 and attributed to an AF-QCP with TN = 0. The TN vs x phase diagram show two distinct regimes that might be related to two different kind of magnetic ordering, which requires further confirmation. The 2D nature of quantum fluctuations is inferred from the magnetic phase diagram where the magnetic ordering close to xc follows linear behavior. Thus, in order to confirm the exact magnetic ordering of the doped compounds, we propose to carry out powder neutron diffraction studies on these compounds.
