dc.description.abstract | The dielectric properties of CuCrO2 bulk and thin films are studied by evaluating the complex dielectric function ε. In addition to the small peak near the Néel temperature 𝑇N, a secondary broad peak is found at high temperatures around 𝑇m=450 K≫𝑇N. As a feature of relaxor ferroelectrics, the maximum temperature 𝑇m increases with increasing frequency. The real part of ε decreases with increasing magnetic field h and the peak at 𝑇N vanishes. The secondary peak becomes smaller and is broadened with increasing magnetic field. ε increases with increasing film thickness. Near 𝑇m, the dielectric function offers a critical behavior expressed by an exponent 𝛾=1.74. Using scaling arguments, critical exponents 𝛽=0.13 and 𝛿=13.38 are deduced. The exponents depend on the film thickness. While β increases, the exponent γ is reduced with increasing film thickness. | eng |
