Crystal structure and non-linear properties of A2(MoO4)3 (A = Eu, Gd, Tb, Dy and Ho)

Magnetic and vibrational properties of Gd2(Mo0.9W0.1O4)3 and Gd1.8Er0.2(MoO4)3

“…The quality of the refinement, estimated from χ 2 , R wp and R p goodness-of-fit parameters, agrees with the values found for other rare-earth molybdates [3,10,11].…”

“…The rare-earth (RE) molybdate compounds of the type RE 2 (MoO 4 ) 3 have been a subject of significant interest since the 1960s due to the connection between their ferroelectric and ferroelastic properties [1]. Generally these materials crystallize in a tetragonal structure above 1000°C, but on cooling, they undergo phase transitions and exhibit orthorhombic Pba2 β′− structure [2].…”

“…Generally these materials crystallize in a tetragonal structure above 1000°C, but on cooling, they undergo phase transitions and exhibit orthorhombic Pba2 β′− structure [2]. As a rule, the ferroelectricity and ferroelasticity in these compounds are strongly connected to their low symmetry [3].…”

“…Recently, studies of magnetism for β-RE 2 (MoO 4 ) 3 where RE¼Gd Tb and Sm showed that their saturation magnetic moments depend on the direction of magnetic field [4][5][6], and in particular for RE ¼Tb it was observed as a giant magnetic anisotropy in the paramagnetic Tb 2 (MoO 4 ) 3 [7]. Furthermore, magnetoelectric switching effects were observed.…”
