I have ploted Oe and Emu/g in Origin and from the slope of high field i have calculated saturation Magnetization. But i dont know how to determine Mr (remanent) and Mc( Coercive Force).
Thanks in advance.
In the Raw data itself, they would have given the saturation magnetization, remanent, and coercive forces if not we have to calculate it from number turns and sensitivity of the Field sed for the instrument. Check the data once
If you do VSM, they will provide all the information. Or else, you can fallow as sunderarajan said.
I wish you good luck.
It is easy to find the remnant magnetization and the coercivity from your M(H) plot (hysteresis loop) obtain by the VSM. I recommend you visiting the following papers which portray the Mr and Hc calculations in two different materials:

when a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed. The amount of magnetization it retains at zero driving field is called its remanence. It must be driven back to zero by a field in the opposite direction; the amount of reverse driving field required to demagnetize it is called its coercivity.
