Abstract The specific heat and resistance of CeCu$_{6-x}$M$_x$ ($M$=Ni,Zn) have been studied in the concentration range where they still retain the orthorhombic structure. The coefficient c of -ln T term in resistance $R=R_0+bT-c\ln T$, as well as the $\gamma$, have been found to vary in opposite directions with increasing $x$ for Ni and Zn substitutions. The physical mechanism is discussed.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
