Of course, this correction must always be made taking into account the contribution of the sample holder (unless the sample to be studied is highly magnetic, therefore this correction can be overlooked only in this case)

For weakly magnetic samples, this is essential!

To do this, simply measure the signal of the sample holder alone ( as a function of temperature under a given weak field, for susceptibility measurements) and as a function of field strength (for isothermal measurements)

These values can be incorporated into a software program that automatically fights the correction by subtracting the sample holder's contribution from the raw signal and giving the sample's own signal.

Good measurements!

I have received the data from the SQUID lab as

1. Sample holder .dat file.

2. My sample including sample holder data without correction.

Now, how can I do the correction manually? Mohamed El Hafidi

You can make the correction by subtracting the sample holder signal (1) from the overall signal (2) (sample + sample holder): (2)- (1)

Thank you .

I have done this exercise.

Now I want to separate the paramagnetic contribution for ferromagnetic contribution. How can I do this?
