Antiferromagnetic 4-d O(4) Model
نویسندگان
چکیده
We study the phase diagram of the four dimensional O(4) model with first (β1) and second (β2) neighbor couplings, specially in the β2 < 0 region, where we find a line of transitions which seems to be second order. We also compute the critical exponents on this line at the point β1 = 0 (F4 lattice) by Finite Size Scaling techniques up to a lattice size of 24, being these exponents different from the Mean Field ones.

متن کامل00 2 High - field magnetization of the 3 d heavy - fermion system
Metamagnetic behavior has been observed in LiV 2 O 4 powder sample around 38 T at 4.2 K. On the other hand, magnetization for oxygen deficient LiV 2 O 3.92 shows no indication of metamagnetism up to 40 T, and shows substantially reduced magnetic moment compared to that of LiV 2 O 4. These results suggest that ferromagnetic interaction is strongly enhanced by magnetic fields in LiV 2 O 4 , where...

Four novel Cu(II) complexes {Na[Cu(4)(hmp)(4)(CHOO)(3)](ClO(4))(2)·H(2)O}(n) (1), [Cu(8)(hmp)(8)(CH(3)COO)(6)](ClO(4))(2) (2), [Cu(4)(hmp)(4)(CH(3)CN)(2)(ClO(4))(2)(H(2)O)(2)](ClO(4))(2) (3), and [Cu(4)(hmp)(4)(CH(3)COO)(2)(H(2)O)(4)](ClO(4))(2)·2H(2)O (4) with Hhmp = 2-(hydroxymethyl)pyridine were prepared by structural modulation at room temperature. Taking advantage of the steric hindrance o...

In the presence of ammonia, the reactions of cyanamide and Cu(II) ions with different organic blocking ligands afford three hydrogencyanamido bridged dinuclear complexes: [(dmbpy)(4)Cu(2)(HNCN)](ClO(4))(3)·H(2)O (1, dmbpy = 4,4'-dimethyl-2,2'-bipyridine), [(phen)(4)Cu(2)(HNCN)](ClO(4))(3)·2H(2)O (2, phen = 1,10-phenanthroline) and [(bpy)(2)Cu(2)(HNCN)(2)(ClO(4))(2)] (3, bpy = 2,2'-bipyridine), ...
متن کاملMagnetic Model for Ba 2 Cu 3 O 4 Cl 2
Ba 2 Cu 3 O 4 Cl 2 consists of two types of copper atoms, Cu(A) and Cu(B). We study the corresponding Heisenberg model with three antiferromagnetic couplings, J AA , J BB and J AB. We find interesting frustration effects due to the coupling J AB .
