Crystal field in praseodymium gallium garnet

High field magnetic anisotropy in praseodymium gallium garnet at low temperatures

“…However, it should be pointed out that the calculated data are not in complete agreement with the experimental results in Ref. [8]. It is shown that the theoretical values are less than the experimental results when the magnetic field is about 0-10 Tesla.…”

“…As is known, some theoretical investigations on crystal field in PrGaG have been performed during the past decades, where it has been pointed out that deducing a set of phenomenological CF parameters is very important to the study of crystal field effect [8,14]. Also, several sets of CF parameters listed in Table 1 have been given in those literatures.…”

“…The first three sets of CF parameters are obtained from Ref. [8], where it is indicated the no. 1 set of CF parameters is much more suitable to the calculation of magnetization curves in PrGaG.…”

“…It is noticed that, recently, Nekvasil et al have given a experimental report on magnetic properties of PrGaG where an obvious magnetic anisotropy under extreme conditions was shown, moreover, a theoretical interpretation was performed [8]. In Nekvasils' calculations, only taking crystal field into account, a set of CF parameters was selected to calculate the magnetization under high magnetic field (up to 15 T).…”
