Magnetocaloric effect in the spin-1/2 Ising-Heisenberg diamond chain with the four-spin interaction

Magnetocaloric effect in the spin-1/2 Ising-Heisenberg diamond chain with the four-spin interaction

The magnetocaloric effect in the symmetric spin-1/2 Ising–Heisenberg diamond chain with the Ising four-spin interaction is investigated using the generalized decoration-iteration mapping transformation and the transfer-matrix technique. The entropy and the Grüneisen parameter, which closely relate t...
