文摘

The Curie temperatures of ferroelectric Ca8-xPbxMBi(VO4)7 solid solutions are chemically controlled from 1070 down to 730–800 K.

Optical SHG non-linear coefficient in Ca8-xPbxMBi(VO4) strongly increase up to 3.3 pm/V at an optimized Pb and Bi concentration.

Structure-property correlations in the whitlockites includes crystal site positions occupancy by two- and trivalent cations.
