Abstract
AbstractIn this work, for the very first time a calculation of the ferroelectric size effect of cone‐shaped nanoparticles (nanocones) was performed. To solve the appropriate Euler–Lagrange equations, a direct variational method was used. An approximate analytical expression for the phase transition temperature dependence on the nanocone volume was derived. We have shown that the transition temperature might be higher by up to a factor of 2.5 compared to bulk materials.
