Peculiarities of optical absorption spectra of NdFe(BO) crystal in magnetically ordered state and at the transition to spiral magnetic phase
V. V. Slavin, I. S. Kachur, V. S. Kurnosov +1
We study experimentally and theoretically optical absorption spectra of neodymium ferroborate in the temperature range K. We show that the temperature dependences of integra…

Magnetic properties of the frustrated decorated Ising chain
D. V. Laptiev, O. O. Krivchikov, Yu. V. Savin +1
Using the Kramers-Wannier transfer matrix method we studied several decorated Ising chains. The exact expressions for thermodynamic characteristics, including the ground state char…

Giant caloric effects in spin chain materials
A. A. Zvyagin, V. V. Slavin
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 t…
