Abstract

The exact initial transverse susceptibility of a mixed spin Ising chain composed of alternating spin-1/2 and spin-S (S > 1/2) atoms has been obtained by a method based on both exact Ising spin identities and a differential operator technique. Numerical results are presented and discussed by selecting the two values S = 1 and S = 3/2.

Transverse susceptibility in spin S Ising chains

Michael F. Thorpe, M. F. Thomsen

It is shown that the transverse susceptibility of a one-dimensional spin S Ising system can be calculated by combining linear response theory with the transfer matrix technique. Closed form expressions for infinite chains are obtained for S= 1 / 2 and S=1, and numerical results are displayed for S= 1 / 2 to S= 5 / 2 .

The zero-field susceptibility of the transverse Ising chain with arbitrary spin

Kazuhiko Minami

The zero-field susceptibility of the transverse Ising chain with arbitrary spin-S is expressed in terms of the eigenvector for the maximum eigenvalue of its transfer matrix. As a result, the exact susceptibility is explicitly obtained for , 1, and can be obtained at least for . The numerical calculations of the susceptibility for arbitrary spin are possible and those for S = 6, 12 and 24 are given. It is also derived that the zero-temperature limit of the susceptibility is independent on spin-S.

Thermodynamics of a Mixed Spin Ising Chain

T. Kaneyoshi

The exact solutions of the spin-spin correlation functions, the internal energy and the specific heat in a mixed spin Ising chain made up of two kinds of alternating magnetic atoms, namely spin-1/2 atoms and spin-S (S > 1/2) atoms with a crystal-field interaction constant D, are derived by the use of Ising spin identities and a differential operator technique. These solutions are valid for arbitrary values of S and D. Some numerical results are given for the specific heat. We find that the results exhibit characteristic behavior which does not follow the Schottky-type when the value of D becomes smaller than a (negative) critical value.

Transverse susceptibility of a double Ising chain

M. A. Yurishchev

The initial static transverse susceptibility is calculated for a double Ising chain whose Hamiltonian is invariant relative to the simultaneous reflection of all spins. The possibility is also noted of finding the imaginary part of the transverse dynamic susceptibility that governs the form of the magnetic resonance spectrum.

The Exact Susceptibility of the Spin-S Transverse Ising Chain with Next-nearest-neighbor Interactions

Kazuhiko Minami

The zero-field susceptibility of the spin-S transverse Ising chain with next-nearest-neighbor interactions is obtained exactly. The susceptibility is given in an explicit form for S=1/2, and expressed in terms of the eigenvectors of the transfer matrix for general spin S. It is found that the low-temperature limit is independent of spin S, and is divergent at the transition point.

An Exact Calculation of the Transverse Susceptibility for an Antiferromagnetic Ising Chain

N. Kunisada, Y. Fukumoto

We study the transverse susceptibility of the fully frustrated antiferromagnetic Ising Δ-chain, extending Minami's transfer-matrix method to the transverse susceptibility of general-type Ising linear-chains [J. Phys. Soc. Jpn. 67 (1998), 2255]. For the transverse fields Γ1 in tip spin sites and Γ2 in bottom spin sites, we calculate zero-field transverse susceptibilities χxtip = lim Γ1 →0Mxtip/Γ1 and χxbottom = lim Γ2 →0Mxbottom/Γ2 while keeping the ratio Γ1/Γ2 fixed, where Mxtip (bottom) denotes the magnetization for tip (bottom) spin sites. Both the transverse susceptibilities follow Curie's law at low temperatures. We also calculate χxbottom(Γ1 > 0), the transverse susceptibility of the bottom spin chain under a finite tip-spin transverse field, to understand the Curie-type behavior in zero-field susceptibility. Using the second-order perturbation theory, we also discuss the Γ1 dependence of χxbottom (Γ1) at zero temperature.
