Magnetic ordering inKDy3F10: A system containing three orthogonal Ising lattices

Paramagnetic properties of cubic RbSm3F10 and KHo3F10

“…Compounds with this structure have been reported for rare earths from Sm through Tb incorporating Rb, and for Tb through Lu incorporating K [2,3]. We have previously observed magnetic order in a number of these materials, including several which contain three orthogonal Ising lattices [4][5][6]. Some of these, surprisingly, are ferromagnets.…”

Magnetic order in the anhydrous cubic nitrates K3Ce2(NO3)9 and Na3Gd2(NO3)9

“…The polarized ground state in the Gd compound is possibly due to a delicate energy tradeoff when the two interactions are combined; this may reflect the fact that the energy splitting between lowest lying dipolar antiferromagnetic and polarized states is typically less than 5%. The addition of exchange could lead under certain circumstances to an inversion and leave a ferromagnetic state lowest, as observed in KDy 3 F 10 [19]. Fig.…”

Electron paramagnetic resonance parameters and local structure for Gd3+ in KY3F10

“…The Y 3+ may be described as occupying the approximate face centers of a simple cubic lattice with a cube edge half the value of the full structure and located at the vertices of a network of corner-sharing octahedra [1,2,16]. Thus, the impurity Gd 3+ is surrounded by eight nearest F − ions forming an antiprism [GdF 8 ] 5− cluster.…”

“…Rare-earth fluorides (KR 3 F 10 , where R=Dy 3+ , Er 3+ , Yb 3+ , denotes rare-earth ions substituting for Y 3+ in KY 3 F 10 ) with KY 3 F 10 structure have attracted a lot of attention due to their novel magnetic properties, e.g., nearly complete (Ising) anisotropy of the magnetic moments along the local symmetry axis (or C 4 axis) and three orthogonal Ising lattices [1][2][3]. In addition, KY 3 F 10 exhibit useful laser and luminescence properties when doped with Er 3+ , Eu 3+ , Ho 3+ and Pr 3+ [4][5][6][7][8][9][10][11].…”
