Opis:: In the paper the possibility of stabilization of the long-range magnetic order in a two-dimensional ferromagnetic with one-ion easy-plane anisotropy is explored. It is shown that at the presence of a small anisotropy in a two-dimensional ferromagnetic the long-range magnetic order is stabilized by magnetoelastic interaction. If one-ion anisotropy is comparable or even exceeds the exchange interaction in the system there exists a long-range non-vectorial quadrupolar tensorial magnetic order.

Opis:: The phase H-P-β diagram of an easy-plane strongly anisotropic antiferromagnet is studied. It is shown that in such a system a realization of the phase with the nonmagnetic order parameter, the so-called quadruple phase, is possible. The realization of this phase is caused by several purely quantum effects, moreover the mechanism of its appearance differs in principle from that of the antiferromagnet or ferromagnet. The possibility of the disappearance of the angular phase (the so-called quadruple ferromagnetic phase) is also shown.

Opis:: Thermal expansion Δl/l(T) and magnetostriction λ$\text{}_{∥, ⊥ }$(H,T) in the pulsed magnetic fields H up to 250 kOe were studied in the single La$\text{}_{1-x}$Sr$\text{}_{x}$MnO$\text{}_{3}$ crystals (x=0.1, 0 .125, and 0.15) at temperatures T=10-320 K. Anomalies in the Δl/l (T) curves were observed near a charge (polaron) ordering (T$\text{}_{p}$) and structural transitions between orthorhombic Jahn-Teller distorted O' phase and high temperature orthorhombic (pseudocubic) O$\text{}^{*}$ one (T'$\text{}_{s}$). A noticeable increase in the field-induced magnetostriction λ$\text{}_{∥, ⊥ }$(H) was revealed in the O' phase at T$\text{}_{p}$

Opis:: Physical properties of $Gd_2Cu_{2 - x}Co_{x}In$ (x = 0.1, 0.2, 0.3) samples are investigated. The paper brings results of X-ray diffraction, magnetometric as well as specific heat studies. It was found that only sample with x = 0.1 exhibits desired crystal structure. Other compositions show existence of impurities due to lack of dissolution Co atoms. For $Gd_2Cu_{1.9}Co_{0.1}In$ sample the Curie temperature of 92.5 K was evidenced. Thus, an enhancement of ferromagnetic correlations with comparison to $Gd_2Cu_2In$ sample was evidenced. It was found that $Gd_2Cu_{1.9}Co_{0.1}In$ sample exhibits magnetocaloric effect within broad temperature range.
