Phrase: Landau theory of antiferromagnetic phase transitions | Statement: [Néel vector, appearsIn, Landau theory of antiferromagnetic phase transitions]

Target entity: Landau theory of antiferromagnetic phase transitions
Context triple: [Néel vector, appearsIn, Landau theory of antiferromagnetic phase transitions]

• A. Landau theory of second-order phase transitions chosen
  Landau theory of second-order phase transitions is a phenomenological framework that explains continuous phase transitions by expanding the free energy in terms of an order parameter and analyzing symmetry-breaking behavior near critical points.
• B. Langevin theory of paramagnetism
  The Langevin theory of paramagnetism is a classical statistical model that explains how the magnetization of paramagnetic materials depends on temperature and applied magnetic field by treating atomic magnetic moments as non-interacting dipoles subject to thermal agitation.
• C. Ehrenfest classification of phase transitions
  The Ehrenfest classification of phase transitions is an early theoretical scheme that categorizes phase transitions by the order of discontinuity in thermodynamic derivatives, such as entropy or specific heat, at the transition point.
• D. Landau–Peierls instability
  Landau–Peierls instability is a theoretical prediction in condensed matter physics that shows how long-wavelength thermal fluctuations destroy true long-range positional order in low-dimensional crystalline systems.
• E. Ginzburg–Landau theory of superconductivity
  The Ginzburg–Landau theory of superconductivity is a phenomenological framework that describes superconductors using a complex order parameter and macroscopic equations to capture phase transitions, coherence length, and magnetic behavior.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
