- New complex oxides based on phosphorus, transition metals, and alkali metals were synthesized by hydrothermal synthesis/high-temperature crystallization: synthetic beussite, alpha- Mn3(PO4)2, Cs2Cu3(H2O)2[B4P6O24(OH)2], Cs2Ni3(H2O)2[B4P6O24(OH)2], Rb2Ni2.5Fe0.5(H2O)2[B4P6O24(OH)2], Cs[BP2O6(OH)2], Cs0.51Mn1.17(H2O)2[BP2O8]*0.45H2O, CsMn[BP2O8(OH)], pollucite analogues Cs2(M,Al)3P3O12 (M=Cu, Mn). Their crystal structures and physical properties were studied. Crystal-chemical correlations of the studied compounds with related phases were revealed.
- The crystal chemistry was studied, topological connections with related compounds were revealed, magnetic and thermodynamic properties of compounds were investigated: howardevancites ACuFe2(VO4)3 (A = Li, Na), rubidium and manganese phosphate RbMn4(PO4)3, a synthetic analog of triploidite Mn2(PO4)OH, rubidium and manganese borophosphate, Rb2.3(H2O)0.8Mn3[B4P6O24(O, OH)2, manganese trivanadate KMn2V3O10, and a number of other phases.
- The physical properties of three polymorphic varieties of Mn3(PO4)2 phosphates were investigated, and the crystal structure-magnetic properties relationships were established. A review of the crystal chemistry and physical properties of transition metal phosphates of the Mn3(PO4)2 family was prepared.

“Novel low dimensional magnets in the phosphate-vanadate systems: synthesis and characterization”, RFBR 18-03- 00908,
- As part of the project, a number of novel compounds with transition metal cations were obtained by the hydrothermal method. They are phosphates: CsMn(H2O)6(PO4), RbMn3(PO4)2, CsMnPO4, Ni2(H2O)2[P2O7], KMn(H2O)2[Al2(PO4)3], Na0.32Ni0.32Ni5.68(OH)3[PO4H0.56]3[HPO4]; vanadates: K2MnV3O10, K2ZnV5O14 and borophosphates: A2M3 (H2O) 2(B4P6O24(OH)2, where A = Cs and Rb, M = (Ni, Fe), Ni, Cu; Cs0.51Mn1.17(H2O)2[BP2O8]•0.45H2O and CsMn [BP2O8 (OH)]. Their crystal structures were established, and their crystal chemical particularities were examined, with the help of the single/powder
X-ray diffraction analysis. Physical properties of the majority of those phases were studied in measuring the magnetic susceptibility, magnetization and heat capacity at low temperatures. Their quantum ground state was discovered. It was established that borophosphates of the A2M3(H2O)2(B4P6O24(OH)2 family, where A = Cs and Rb, M = (Ni, Fe), Ni, Cu and aluminophosphate KMn(H2O)2[Al2(PO4)3] are paramagnet up to 2 K. β -CsMnPO4, K2MnV3O10 and Ni2 (H2O)2[P2O7], transform into an antiferromagnetic ordered state at low temperatures. A nontrivial magnetic behavior was found for borophosphate Cs0.51Mn1.17(H2O)2[BP2O8] • 0.45H2O, namely, the magnetization plateau and magnetocaloric effect at low temperatures. This behavior is associated with the presence of tetrameric manganese clusters in its crystal structure. A low-dimensional magnetic behavior was established for the ellenbergerite-like phase Na0.32Ni0.32Ni5.68(OH)3[PO4H0.56]3[HPO4] and RbMn4(PO4)3, which is characterized by a high value of the frustration parameter (|Ɵ|/TN> 10).
“New promising materials for information and alternative energy-saving technologies”, NUST MISIS, No. K2-2020-008,
- Throughout the project, new compounds/previously unexplored from different chemical classes were obtained and characterized in magnetic susceptibility and heat capacity measurements: Cs2CuAl4O8, Co(NO3)2, Pb2Cu10O4(SeO3)4Cl7, Pb2Cu10O4(SeO3)4Cl7, LiCuFe2(VO4)3 and NaCuFe2(VO4)3, Ni2(H2O)2[P2O7], Li2MnTeO6, etc. Their quantum ground state was established. Conclusions were made about the prospects of using materials based on the studied compounds in information and energy-saving technologies.
“Quantum cooperative phenomena in transition metal oxides and chalcogenides”, NUST MISIS, No. K2-2017-084,
- As a result of the project, the physical properties of a number of new oxygen-containing compounds and transition metal chalcogenides were investigated, and their quantum ground states were established at low temperatures. This includes: MnSb2O6, KMn2V3O10, RbMn4(PO4)3, Rb3Ni2(NO3)7, FeSexS1-x with a sulfur content of up to 19%.
RFBR No. 17-52- 45014 IND_a “Topological phase transitions in quasi-two-dimensional magnets”,
- As part of the project, a number of low-dimensional, including the first synthesized, magnetics that are promising in terms of implementing topological (swirling) states were examined. Those objects include the new family of quasi — two dimensional A2MnXO4 (A = Li, Na, Ag; X = Si, Ge) magnetics, as well as samples with a Li3Ni2SbO6 type of honeycomb type system, Cu3Yb(SeO3)2O2Cl Kagome lattice and two — dimensional triangular layers in TlFe(MoO4)2. The structure of new objects was refined by
X-ray, neutron-diffraction and synchrotron analysis. Detailed studies of the magnetic properties of all the mentioned objects were carried out, the main parameters of the magnetic and elastic subsystem of new images were determined. All studied compounds show a pronounced two-dimensional or one-dimensional character of spin correlations in both static magnetic characteristics and spin dynamics.
