- Аннотация: PbCu(SeO4)(OH)2 , the selenate sibling of the mineral linarite has been synthesized hydrothermally, investigated in measurements of magnetization M , specific heat C p and dielectric permittivity ε , and analyzed within density functional theory formalism. This quasi-one-dimensional compound evidences formation of a short-range correlation regime at T* ~ 8 K and experiences a long-range magnetic order at TN = 4.3 K. The magnetization saturates of the level 1 µB is reached at µ0H flip ~ 16 T preceded by a jump at µ0H flop = 2.4 T. Additionally, there are multiple indications on the formation of additional electrically active phase just above the Neel temperature which allows considering PbCu(SeO4)(OH)2 as a multiferroic system.
