Dear Synge,
no I don't have magnetic field in z direction, but looper results always gives a finite Magnetization in the z direction.
also I noticed that if we define the model like this H=-J \sum_{i,j}S^{x}_{i}S^{x}_{j}-h \sum_{i}S^{z}_{i} the looper doesn't work, I don't know why?
Thanks, Zhian.

@Synge I took it from Magnetization density, I think also Magnetization in z
direction is not zero,
ok, thanks I will try that.
Strange. Do you have a finite magnetic field along the z-axis, too?

Dear Zhian,
Could you post your lattice, model, and parameters?
