Structural, optical-vibration and magnetic properties of tetragonal lanthanide pyrogermanates obtained by molten-salt synthesis

•Lanthanide pyrogermanates were synthesized by molten-salt synthesis.•Optical-vibration properties were examined by Raman scattering.•Dy2Ge2O7 shows a PM-AFM transition around 2.5 K.•Long-range magnetic ordering were observed for Tb, Ho and Er down to 2 K.•Magnetic properties were coherent with a ma...
