Magnetic phase transition in layered CsGd(MoO4)2

Crystal chemistry and luminescence properties of red-emitting CsGd1−xEux(MoO4)2 solid-solution phosphors

“…It should be noticed, however, that the existence of CsGd-(MoO 4 ) 2 molybdate has long been known, and some thermal and magnetic properties were observed in several studies. [24][25][26][27] Contrary to that, the properties of CsEu(MoO 4 ) 2 are unknown in the literature.…”

Slow Magnetic Relaxation in the Highly Anisotropic Layered Crystal CsNd(MoO4)2

“…The latter was subtracted using a procedure based on the modification of the specific heat of CsGd(MoO 4 q 2 . Previous studies in zero magnetic field [8] showed that at temperatures above 10 K, only lattice vibrations contribute to the CsGd(MoO 4 q 2 specific heat. Thus, using the ratio of Gd to Nd molar mass, being equal to 1.02, lattice contribution in CsNd(MoO 4 q 2 was estimated as C LAT (Nd)=1.02 ¢ C LAT (Gd).…”

Impact of the crystal electric field on magnetocaloric properties of CsGd(MoO4)2

“…Energy scheme (2) corresponds to the local symmetry D 2 with CEF parameters given in Table. 1 low-temperature data below 2 K [26] completed with the current measurements performed above 2 K. It is clear that the description of the data is not sufficient, pointing at the overestimation of the CEF influence. Thus, the effect of magnetic correlations and/or other low-symmetry terms in H CEF should be included.…”

“…Besides their potential use in the optoelectronic devices at room-temperature applications, the compounds possess interesting magnetic properties at low temperatures [24,25]. Previous low-temperature studies [26,27,28,29,30,24] considered this material as a quasi-one dimensional dipolar magnet with a magnetic phase transition to the ordered state at T C = 0.45 K. The effective strength of dipolar interactions was estimated in the form of the effective intra-chain coupling parameter J/k B ≈ 0.6 K and interchain coupling J ′ < 0.03 J [27].…”

“…Dashed and dotted lines correspond to the CEF model with the axial symmetry for B 0 2 = -0.089 K and B 0 2 = -0.0557 K, respectively. The dashed-dotted line represents the lattice contribution 1.98×10 −3 T 3[26]. (b) Temperature dependence of the phonon mean free path of CsGd(MoO4)2 in zero magnetic field[24].…”
