Acoustic properties (ultrasound velocity and attenuation) and magnetostriction were measured in pulsed fields up to 60 T applied along the c axis of Tm₂Co₁₇ single crystal. Similar to Er₂Co₁₇, the transition in Tm₂Co₁₇ is ...

We report results of magnetic and ultrasound studies of the sulfide spinel CoCr₂S₄ , for which the multiferroicity has recently been suggested. Clear anomalies in the magnetic and acoustic properties have been observed at ...

Optical characteristics of a single nanoparticle, coupled to the one-dimensional quantum molecular aggregate is studied. Depending on the values of the coupling of the particle and its own frequency, with respect to the ...

It is shown that for finite cyclic systems described by two band Hubbard Hamiltonian with strong electron repulsion the reduction to effective t–J model may give incorrect description of the ground state symmetry due to ...

Исследован спектр рамановского рассеяния света в монокристалле KDy(MoO₄)₂ в области частот 3–1000 см⁻¹ и диапазоне температур от 2 до 300 К, включающем температуру структурного фазового перехода типа кооперативного эффекта ...

Работа посвящена выяснению природы магнитного состояния слабо анионизбыточного манганита лантана LaMnO₃₊δ (δ ≈ 0,0375). Подробно изучены особенности температурных и полевых зависимостей магнитного момента монокристаллического ...
