Electrical properties are examined by complex impedance (Z*), dielectric permittivity (ε*), and ac conductivity studies at different frequencies (10 kHz-5 MHz) and temperatures (253-333 K). The contribution of grain and grain boundary has been explained by a different theoretical model. The variable temperature magnetic susceptibility data for compound 1 were recorded between 300 and 2 K. The shape of the curve (χM T vs T) indicates dominant antiferromagnetic coupling, which results from the interaction between the copper(II) atoms.7 p.application/pdfeng(c) American Chemical Society, 2019PolímersMagnetoquímicaPolymersMagnetochemistryinfo:eu-repo/semantics/article6950522021-05-27info:eu-repo/semantics/openAccess31956774
