I'm start working in Cryogenic system, particularly using VSM. I am unable to demagnetize the sample. How to do?

When I insert the sample inside VTI, generally, it should show that the magnetic moment is zero(in emu) when the applied magnetic field is zero. But in zero magnetic field displaying magnetic...
