Please define your acronyms.

PE = polyethylene?; PE = Physical Education?; PE = Public Enemy?; PE = Planet Earth?; PE = Phenylephrine?; PE = Prostate Enlargement?; PE = Pancreatic Enzyme; PE = Phycoerytherin?; PE = Pure Enantiomer etc etc

From where comes your signal?  The railway?

Judging from the topics of Alaka Panda, this is about the measurement of the polarization as a function of electric field.

What do you expect? The names of the instruments, help in combination of your equipment? We know nothing about the material you want to explore, conditions, etc.

I think I have understood your question as follows;

You have a small solid sample. (definitely not a powder or a liquid).

and you want to do a PE hysteresis loop measurement. Such measurements are done only on solid samples, and not on powders, or mixing them in any matrix.

For making such measurement, yes you can do them on small tiny samples.

You need the sample in the form of a small capacitor. A defined area and thickness.

In other words this is known as a parallel plate capacitor. You have to apply electrode on the opposite faces.

You can have a sample as tiny as (3mm x 3mm area), and the thickness can be around 0.5 to 1 mm, and you should be able to do PE hysteresis loop measurements.

Polarization-Electric field loop (PE loop) 

response  from the sample when electric field is applied.

I hope now after knowing the details you will able to help me out Alan F Rawle Sir

Paweł Wawrzała Sir I would like to know any matrix in which I can disperse my sample and make a pellet to get the measurement done. My question is "Is it possible ? If yes then can you suggest any matrix? and yes the material I am working on is Bi2Fe4O9 

K. Sreenivas Sir Thank you very much. Your answer is really helpful. Can you please help me out deciding the matrix I should use for my sample Bi2Fe4O9? Or in general the matrix use for PE loop measurement.
