“…Using the wavefunctions of CF levels of table 1, we calculated the g-values of ErDG. These values are g = 10.314 and g ⊥ = 0.0, which are very different from those reported for other Er 3+ compounds [42][43][44] because in this case the M j value of the principal component of the lowest level is 15/2, which is consistent with the optical result [14].…”

Measurement of the magnetic susceptibilities and their anisotropy in single crystals of ErDG in the temperature range of 300-22 K are reported here for the first time. The anisotropy value became constant at and below 32 K and this was associated with a possible rotation of each of the three structurally equivalent lanthanide sites in the unit cell without destroying the overall trigonal symmetry of the crystal field (CF), as also observed earlier in NdDG and . CF analysis was performed and the fitted CF parameters were found to be close to the values reported from optical absorption study. The g-values were calculated and found to be and . The calculated values of Schottky specific heat showed a maximum at about 100 K.

“…More practical winding distributions have been proposed for the design of deflection units for a variety of applications including electron microscopes, vidicons, etc. (6)(7)(8)(9). In these cases however, the radius of the region in which the field is to be used is much smaller than the radius of the cylinder on which the currents are distributed.…”

High‐order coils as transmitters for NMR imaging

High-order radiofrequency transmitter coils are described that permit, in the context of NMR imaging, a knowledgeable trade-off between coil complexity and the degree of inhomogeneity over a specified volume of space. A mathematical formulation of high-order coils is developed for an axially symmetric polarizing dc field and transverse rf field. The field is created by a number of longitudinal current filaments with equal angular separations on the wall of a cylinder. In its most general form, each current can be independently specified. Circularly or linearly polarized fields can be created. Quadrature and saddleshaped coils emerge as special cases of the general formulation. The development has been tested experimentally and good agreement found. High-order coils can also be used as receivers, permitting more equal weighting of the sensitivities of each pixel.
