Hysteresis of MnZnSb

[bhat umar]

Hello everyone 

Can you please help me in simulating the hysteresis curve of MnZnSb Ferromagnetic material. I ran test calculation for the same and I am getting some noisy plot not the hysteresis  curve.

One possible cause might be use of a low damping.  A higher damping may be need for the hysteresis loop as mentioned in the past post at [1].

For example, a hysteresis loop for Ni with damping of 0.001 looks quite noise and doesn't show a loop.  On the other hand, a loop is seen with a damping of 1 as seen in the simulated output below.  There could be other possible causes.  The past posts [2] and [3] also mention some possible causes.
