We also restrict our consideration to the vicinity of the critical point (near the phase transition). either positive (paramagnetic) or negative (diamagnetic). Register; Studyrankersonline. The magnetic susceptibility is negative for . 1. The Néel temperature is very high, 823 K, and the magnetic susceptibility has been found by Teranishi (1961) to be relatively independent of temperature. Another important thing:- Landau Quantization Landau Quantization tells us that in a magnetic field, almost everything inside an atom changes. We set the concentration of magnetic atoms to p = 1.
