Microhardness of the Yb x Y 1 x InCu 4 alloy system: the influence of electronic structure on hardness [link]Website  abstract   bibtex   
We show that the Vickers microhardness, measured on flux grown single crystals of the YbxY1-xInCu4 alloy system, although sample dependent, exhibits clear concentration dependence; it increases with decreasing x. Such a dependence is not expected because the cubic lattice parameter increases with decreasing x and one expects then a decrease of hardness with decreasing x. Also, such a concentration dependence is in accordance with neither the Mott-Nabarro theory nor other known experimental results. We ascribe the observed dependence to the change of the electronic structure of the YbxY1-xInCu4 alloy system with x.
