My question is about 2-dimensional Fermi gas of electrons.

  1. What is magnetic susceptibility when $T<<T_F$ (where $T_F$ is Fermi Temperature)


  2. What is the ratio between Pauli and Curie spin susceptibilities?

This sounds a little like homework-- the calculation is straightforward if you know the Landau solution for a particle in a magnetic field (it is contained in most quantum mechanics textbooks) and the standard electron magnetic moment. – Ron Maimon Jan 17 '12 at 5:45
@RonMaimon: yes, it is. I'm new to this forum and was not familiar to the conventions. – Shalandeh Jan 17 '12 at 6:00
@RonMaimon: could you be more specific? in which textbooks I can look them up? – Shalandeh Jan 17 '12 at 6:03
Start here. . I am sure it's in Sakurai and Landau and Lifshitz, perhaps also in Dirac. – Ron Maimon Jan 17 '12 at 6:24
Chapter 31 in "Solid State Physics" by Ashcroft and Mermin. – Maksim Zholudev Jan 17 '12 at 14:30
