Question

For two types of magnetic materials $A$ and $B$, variation of $\frac{1}{\chi}(\chi:$ susceptibility $)$ vs. temperature $T$ is shown in the figure. Then

• A. $A$ is diamagnetic and $B$ is paramagnetic
• B. $A$ is feromagnetic and $B$ is diamagnetic
• C. $A$ is paramagnetic and $B$ is feromagnetic
• D. $A$ is paramagnetic and $B$ is diamagnetic

Answer 1

Answer: (B)

Actually graph A represents antiferomagnetic material.
