Polarization Loop Tracer

Polarization loops measurement is a crucial test for the presence of ferroelectric state. The TF Analyzer 2000 (AixACCT, Aachen, Germany) is one of the best analyzers of ferroelectrics and related materials (including multiferroics) in bulk crystals, ceramics, thin- and thick film forms. In our configuration we use TF Analyzer 2000, TREC 610 D High-voltage Supply/Amplifier/Controller and Oxford continuous-flow Cryostat.

 

measured example:
