Single crystal magnetic properties and crystal field investigation of Ho(BrO3)3·9H2O

Crystal Field Theory of Magnetic Behaviour of Er2(SO4)3·8H2O

“…Finally we stress that the major emphasis of the present investigation is to demonstrate that one has to use the complete basis in contrast to the partial basis as is customary with magnetic workers [16][17][18][19][20][21] and diagonalize the energy matrix incorporating all the interactions simultaneously. This is necessary to get the correct set of parameters as has already been shown by us for other system [8].…”

Magnetic measurements on the single crystals of Nd(BrO3)3·9H2O and a crystal field investigation of its properties

“…As the effective valency (e) of the rare earth ions varies from ion to ion in a particular type of host, we express the effective CF parameter B kq as where A kq is now ion independent and may be treated as the intrinsic parameter for a particular type of host lattice. Neogy and his coworkers [6][7][8][9][10][11][12] have proposed the CF parameters for most of the members of the rare earth series in bromate host from the fit to the available observed Stark energies and the magnetic properties studied by them. These parameters are exploited to find the intrinsic parameters (using relation (2) above and keeping the scaling parameter t to be unity) for all these systems.…”

“…Though some workers [1][2][3][6][7][8][9][10][11][12] assumed a hexagonal unit cell for the analysis of their data, others [4,5] suggested a low symmetry space group. The coordinates derived from the space group do not differ significantly [5] from those derived from hexagonal site symmetry and it has been concluded [5] that the choice of low symmetry is not definite owing to experimental uncertainties.…”

“…Rare earth bromate enneahydrates, REðBrO 3 Þ 3 Á 9H 2 O ðREBRÞ form an isomorphous series and extensive studies of their crystal structure [1][2][3][4][5], and magnetic properties [6][7][8][9][10][11][12] have been carried out in the recent years. The magnetic ordering [13,14], thermal properties [15] and absorption spectra [16][17][18][19][20][21] of some of the compounds of the series are also available in the literature.…”
