The rare earth vanadates have long been studied for their interesting magnetic properties and cooperative Jahn–Teller distortions. In the main, most of this work has been carried out at temperatures down to 1 K or so (e.g. Gehring and Gehring 1975). In this review NMRON, and other low temperature experiments in the mK regime, are presented and discussed. It will be argued that the low temperature properties of these compounds are just as interesting as their high temperature counterparts. In general, the nuclear and electronic wavefunctions become intermixed, leading to a variety of interesting physical effects, such as enhanced nuclear magnetism, quadrupolar induced intermediate state re-orientation etc. These effects have, in turn, spawned new methods for the investigation of magnetic structures, and thermometric detection of NMR both by internal and external thermometers. Several experiments are suggested, including magnetic refrigeration, Mössbauer, EPR in the ≈30 GHz range, in addition to thermometric NMR and NMRON.

“…The resultant y-ray anisotropy data, which is presented in the form of a statistical tensor plot of p\ against p i, is shown in figure 4. From an examin it will be observed th a t all the experimental points are on a straight line of slope p \lp l = -f This is precisely w hat one would expect from a pure quadrupole in ter action P directed along the c-axis of the H oV 04 crystal (see, for example, figure 4 of Bowden et al 1979). However, a similar result is also obtained if the H oV 04 crystal possesses equal numbers of a-and a'-antiferromagnetic domains, as illus trated in figures 1 (a) and 1 ( 6) respectively.…”

The y-ray emission anisotropy from the long-lived isomer 166m Ho ( I = 7) has been investigated in single crystals of the enhanced nuclear paramagnet HoVO 4 . From measurements in fields up to 2 T and temperatures between 45 and 65 mK, the nuclear magnetic moment of 166m Ho is determined as 3.60(5) pN. After adiabatic demagnetization, temperatures of approximately 1 mK were reached, and the nuclear ordered state has been studied. The results confirm that it is anti-ferromagnetic, and that the ordering is consistent with the predictions of Bleaney (1980), based on an effective field treatment of the dipole-dipole interaction between the enhanced nuclear moments. In particular, the spin-flop phase has been identified in fields of order 10 -2 T.

“…Pearson and Williams (226) derive an expression for the absorption line shape of such absorbers in large applied magnetic fields. Bowden et al (51) tabulate useful statistical tensors for this case. The computation time of this type of spectra can be reduced by symmetry considerations, as is done by Hasselbach and Spiering (136).…”
