Wideband Dielectric Spectrometer

Dielectric constant anomaly near a phase transition temperature is the first and most important “fingerprints” of ferroelectric. Usually a complete characterization of dielectric properties of ferroelectrics and related materials (including relaxors, incipient ferroelectrics, multiferroics and new promising piezoelectric crystals for SAW applications) demand measurements in wide temperature- and frequency ranges. In our configuration we use a Solartron SI 1260 Impedance/Gain-Phase Analyzer, a MESTEC Dielectric Module DM 1360 (Transimpedance amplifier) and a Oxford continuous-flow Cryostat.

measured example:

Features:

• Frequency range 1 MHz – 32 MHz
• Temperature range:
• 4.2 K – 380 K (Cryostat system)
• 295 K – 600 K (Extra furnace)
  

• Dielectric constant (Re and Im parts, tan (d)), Impedance, Admittance, Gain-phase measurements
• Software for circuits- and relaxation parameters simulations and fitting.
