The variation of susceptibility (χ) with absolute temperature ( T) for a paramagnetic material is represented as: (a) (b) (c) (d)

Answer: (a). Curie law: χ = C/T = C·1/T. So χ versus 1/T is a straight line through the origin with positive slope C. So the answer is (a).

The variation of susceptibility $(\chi)$ with absolute temperature ( $\mathrm{T}$ ) for a paramagnetic material is represented as:

Show answer and solution

Answer: (a)

Curie law: $\chi = \dfrac{C}{T} = C\cdot\dfrac{1}{T}$ .
So $\chi$ versus $\dfrac{1}{T}$ is a straight line through the origin with positive slope $C$ .
So the answer is (a).
