B-H (HofB) curve definition for permanent magnets

I am using the 3.5a version since it is still providing the accuracy that I need but I have to follow the new version for internal compability, therefore I am trying to transfer my non-linear magnetics problem to 4.2.
In the 3.5a version defining a H as a function of B function for the permanent magnet and from subdomain settings selecting H=f(B) constitutive relation and typing in HB(Br_emqa[1/T])+Hc and HB(Bz_emqa[1/T]) depending on the magnetization direction of the permanent magnet was working like a charm.
The same trick failed in the 4.x series. I wonder if there is anybody who actually used a HB curve of a permanent magnet in combination with a non-linear HB curve of a ferromagnetic material and can share the model with the rest of the community?
Thanks in advance,
Onur
Please note: I have gone through the model database and could only be able to find HB applications for non permanent magnet structures.
