Please help me with your kind suggestion regarding following questions.
How the MH curve will be and how the effect of high field (at room temperature) will affect MH curve for these different type of antiferromagnetic (A, C and G type) .
What will be the basic difference between the paramagnetic and antiferromagnetic MH curve up to 9 Tesla?
Note: the Neel temperature is well above (640 K) and spin flip field is high (18T).
MH curve will show hysteresis if there is saturation magnetization. Otherwise MH curve will be a line like in paramagnets. An antiferromagnet below Neel temperature is likely to behave same way as a ferromagnet, but having a transverse and longitudinal loop- one will have loop area reducing with decrease in temperature the other remaining practically constant.

At very high field the antiferromagnets undergo metamagnetic transitions (spin flip transition). But these are generally apparent at field as high as 12 T.
