The physico-chemical characters of Yb<sub>14</sub>MnSb<sub>11</sub> doped by Ln<sup>3+</sup> (La-Sm)
The Yb<sub>14</sub>MnSb<sub>11 </sub>and solid solutions Yb<sub>14-x</sub>Ln<sub>x</sub>MnSb<sub>11</sub> (Ln=La-Sm; x= 0.1; 0.3; 0.5; 0.7; 0.9) were as single crystals via Sn flux were grown. All phases crystallized in the tetragonal structure type, Ca<sub>14</sub>AlSb<sub>11</sub>. The maximum amount of Ln was determined from wavelength dispersive microprobe analysis to be x≈0.45. Data on structure, melting point, thermal dilation in this paper are presented.
