Ising chains properties at low temperature extended analysis

الملخص EN

The transfer matrix method is used to describe the properties of the random bond of a simple periodic frustrated Ising chain in a uniform magnetic field.

Doman and Williams (1982) are found expressions for the thermodynamic functions of the system at low temperature.

Their methods is extended to apply to a system of five-antiferromagnetic bond Ising chain terminated by a ferromagnetic bond at low temperatures.

New expressions for the magnetization, energy, and entropy as a functions of magnetic field is found.

All results are in agreement with the previous results.
