Giant caloric effects in spin chain materials

Autor: Zvyagin, A. A., Slavin, V. V.

Publikováno v: Phys. Rev. B 109, 214438 (2024)

The giant electro- and elasto-caloric effects in spin chain materials are predicted. The theory is based on the exact quantum mechanical solution of the problem. It is shown that the giant jumps in the entropy and the temperature caused by the calori
