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…
Tricritical fluctuations and elastic properties of the Ising antiferromagnet UIrSi
Tetiana Haidamak, Jaroslav Valenta, Jiří Prchal +6
Elastic constants, thermal expansion, magnetostriction and heat capacity measurements were performed with and without applied magnetic field on a single crystal of UIrSi. The e…
Magnetic Field tuning of low energy spin dynamics in the single-atomic magnet Li(LiFe)N
S. A. Braeuninger, A. Jesche, S. Kamusella +5
We present a systematic 57Fe-Moessbauer study on highly diluted Fe centers in Li2(Li1-xFex)N single-crystals as a function of temperature and magnetic field applied transverse and…
Observation of the novel type of ordering: Spontaneous ferriquadrupolar order
A. A. Zvyagin, K. Kutko, D. Kamenskyi +3
Using Raman and infrared spectroscopies the spontaneous ferriquadrupolar ordering has been observed in the rare-earth-based system KDy(MoO). Ordered quadrupoles in the elec…
Dynamical quantum phase transitions
A. A. Zvyagin
During recent years the interest to dynamics of quantum systems has grown considerably. Quantum many body systems out of equilibrium often manifest behavior, different from the one…
Electron Spin Resonance in a Spin-1/2 Heisenberg Strong-rung Ladder
A. N. Ponomaryov, M. Ozerov, L. Zviagina +8
Cu(CHN)Cl, a strong-rung spin-1/2 Heisenberg ladder compound, is probed by means of electron spin resonance (ESR) spectroscopy in the field-induced gapless phase ab…
