Theoretical Analysis of the Reduction of Neel Temperature in La $_{2}$ (Cu $_{1 - x}$ Zn(or Mg) $_{x})$ O $_{4}$

T. Edagawa, Y. Fukumoto, A. Oguchi

Using Tyablikov's decoupling approximation, we calculate the initial suppression rate of the Neel temperature, $R_{I S} = - l i m_{x - > 0} T_{N}^{- 1} d T_{N} / d x$ , in a quasi two-dimensiona…

Ground-State Phase Diagram of the XXZ Model on a Railroad-Trestle Lattice with Asymmetric Leg Interactions

Masawo Nakane, Yoshiyuki Fukumoto, Akihide Oguchi

Using the bosonization and level spectroscopy methods, we study the ground-state phase diagram of a XXZ antiferromagnet on a railroad-trestle lattice with asymmetric leg interactio…
