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...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | 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 to the magnetocaloric effect, are exactly calculated to compare an ability of the system to cool in the vicinity of different field-induced ground-state phase transitions during the adiabatic demagnetization.
Дослiджено магнетокалоричний ефект у симетричному ромбiчноподiбному ланцюжку Iзiнга-Гайзенберга
iз чотириспiновою взаємодiєю Iзiнга, використовуючи узагальнене декорацiйно-iтерацiйне перетворення i метод трансфер-матрицi. Ентропiя i параметр Грюнайзена, який тiсно пов’язаний з магнетокалоричним ефектом, обчислено точно для того, щоб порiвняти здатнiсть системи холонути в околi рiзних
фазових переходiв, iндукованих полем, пiд час адiабатичного розмагнiчення.
