Thermodynamic and optical properties of new langasites Pr3CrGe3Be2O14 and Pr3AlGe3Be2O14

•No long-range magnetic order was found in Pr3CrGe3Be2O14 langasite down to 0.4 K.•Isolated 1D chains of S = 3/2 Cr3+ are situated perpendicular to 2D Kagomé -layers of Pr3+.•Crystal-field splitting of Pr3+ levels explains Schottky anomaly in specific heat. [Display omitted] We present the results o...
