New nanocomposite compounds containing alternating layers of molybdenum disulfide and organic compound (dyes, polyvinyl alcohol) have been synthesized using sigle-layer dispersions obtained by exfoliation of bulk MoS₂ crystals. The formation mechanism of those compounds as weel as their structure are discussed. The data on photoelectric sensitivity of the system consisting of MoS₂-polyvinyl alcohol nanocomposite and some photoconductive polymers are reported.

An influence of thermal processes rate on temperature dependence of complex magnetic susceptibility x = x' — ix" in ceramic perovskites La₁₋ₓSrₓCoO₃ (x = 0.15; 0.25; 0.35) has been studied. At increasing cooling rate, the x value grew up as compared to the value obtained under slow (equilibrium) temperature variation. This effect is explained by thermomagnetic component (∂M/∂T)(∂T / ∂t) of x value, which is due to strong dependence of magnetization M on temperature T near the Curie point.

Theoretical energy calculation has been carried out for domain walls (DW) of several types with different gyration angles of the magnetization vector in ferrite-garnet crystals with mixed anisotropy (presence of the uniaxial EK and cubic anisotropy EK). The DW orientations satisfying to the energy minimum have been determined. It is shown that at parameter v = KU/K₁, the 1-st type DW (the magnetization vector in the neighboring domains have the same positive projection onto the axis [111], the normal to the film surface) are transformed into the 2-nd type DW (the projections of opposite signs, the angle between magnetization vectors being distinct from 180°).

Two series of novel ferromagnetic shape memory alloys, Ni₅₀₊ₓMn₃₇₋ₓSn₁₃ and Ni₅₀₊ᵧNm₃₉₋ᵧSn₁₁ were characterized by differential scanning calorimetry and magnetization measurements. The results obtained showed that the substitution of Mn for Ni results in an increase of martensitic transformation temperature Tm. The trend to Tm increase is not observed in the alloys with x, y > 2 at %. The results of magnetization measurements evidence complex magnetic properties of these compounds.
