Question

Choose the correct reciprocal susceptibility $(1/\chi)$ vs. temperature (T) plot for paramagnetic substances above the critical temperature : 

 

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

For $1/\chi$ vs $T$ plots: Ideal Paramagnet = passes exactly through the origin ($T=0$). Ferromagnet above $T_c$ = positive intercept on T-axis ($T = T_c$). Antiferromagnet above Neel temp = intersects the negative T-axis (extrapolates to $T = -\theta$).

Answer 1

The Correct Option is D
