Abstract
Alkali metals (Na, Rb or Cs) co‐doped with fiber‐ and bulk‐shaped KNbO~3~ single crystals were grown using two original methods by means of doping together of small ionic Na and large ionic Rb or Cs into KNbO~3~. Single‐phase crystals could be grown with an orthorhombic system at room temperature as well as pure KNbO~3~. Piezoelectric and ferroelectric property changes by the co‐doping of Rb or Cs with Na were estimated using d~33~ values and a polarization‐electric field hysteresis curve in fiber‐ and bulk‐shaped crystals.
