| Summary: | The paper presents the results of studies of the linear and nonlinear dielectric properties of (R) -3-quinuclidinol embedded in porous aluminum oxide with a pore size of 300 nm, in comparison with the properties of bulk (R) -3-quinuclidinol. A decrease in the Curie temperature in the nanocomposite, both upon heating and cooling, in comparison with a bulk sample is revealed. A decrease in the phase transition temperature can be interpreted on the basis of known theoretical models for ferroelectric small particles. |
