Energy spectrum of bound-spinons in the quantum Ising spin-chain ferromagnet
S. B. Rutkevich
We study the excitation energy spectrum in the S=1/2 ferromagnetic Ising spin chain with the easy axis z in a magnetic field h={h_x,0,h_z}. According to Wu and McCoy's scenario of…
Multiphoton Transitions in a Spin System Driven by Strong Bichromatic Field
A. P. Saiko, G. G. Fedoruk, S. A. Markevich
EPR transient nutation spectroscopy is used to measure the effective field (Rabi frequency) for multiphoton transitions in a two-level spin system bichromatically driven by a trans…
Temperature Hysteresis of Magnetization in Lanthanum Manganite
A. P. Saiko, S. A. Markevich
We propose an explanation for the experimentally observed temperature hysteresis of magnetization in single crystals of lanthanum manganite (La0.8Sr0.2MnO3). The phenomenon is inte…
Influence of Co spin-state on optical properties of LaCoO and HoCoO
L. V. Nomerovannaya, A. A. Makhnev, S. V. Streltsov +6
Optical properties of the isoelectronic compounds LaCoO and HoCoO has been experimentally and theoretically investigated. We've measured the real and imaginary $ε_…
