“…The moment arrangement is ferromagnetic, with all Nd and Fe moments parallel to the c axis of the tetragonal cell. This configuration is in accord with the general observa tion 8 that light rare earth and TM moments align fer romagnetically in R TM materials. The average iron moment is near saturation at 300 K, while the Nd mo ments are 1μB.…”

Determination of the crystal structure of Nd2Fe14B, a new ternary phase, is reported. It has recently been demonstrated that permanent magnets having large co ercivities and energy products can be formed from this phase, underscoring its potential technological impor tance. We relate the crystal structure and intrinsic mag netic properties by considering analogies with previously known rare earth transition metal materials.

“…There could be some difference between bulk and fragment data as the former incorporates a distribution of T c but the latter may have only a smaller subset of this distribution. This usually happens in the 10 systems that are nonstoichiometric, in which compositional gradients may occur at different length scales. Since DyCo 2 is a stoichiometric compound, it is most likely that a small fragment should remain representative of the bulk.…”

“…9 The choice of R affects the lattice parameter, and as a result the bulk magnetic behavior via 4f-3d exchange. 10 Furthermore, the lattice parameter, a, can be tuned such that a small change in applied field, temperature, and/or pressure can induce magnetic order (7.05 Å < a < 7.22 Å), 6,11 and an associated volume change (or distortion) occurs to reduce the increase in energy due to overlap of 3d bands. If that volume change is sufficiently large, the phase transition will be first order 12 and itinerant electron metamagnetism occurs.…”

Identifying the critical point of the weakly first-order itinerant magnet DyCo2with complementary magnetization and calorimetric measurements

We examine the character of the itinerant magnetic transition of DyCo 2 by different calorimetric methods, thereby separating the heat capacity and latent heat contributions to the entropyallowing direct comparison to other itinerant electron metamagnetic systems. The heat capacity exhibits a large lambda-like peak at the ferrimagnetic ordering phase transition, a signature that is remarkably similar to La(Fe,Si) 13 where it is attributed to giant spin fluctuations. Using calorimetric measurements we also determine the point at which the phase transition ceases to be first order: the critical field, µ 0 H crit = 0.4±0.1 T and T crit = 138.5±0.5 K, and we compare these to values obtained from analysis of magnetization by application of the Shimizu inequality for itinerant electron metamagnetism. Good agreement is found between these independent measurements, thus establishing the phase diagram and critical point with some confidence. In addition we find that the often-used Banerjee criterion may not be suitable for determination of first order behavior in itinerant magnet systems. PACS number(s):

“…The RT 3 compounds where R is rare earth and T is a transition metal have been previously studied very intensively [1][2][3][4][5][6][7]. The whole series indicate very interesting magnetic properties due to the combination of 3d itinerant and 4f localized magnetism.…”

“…Among quite large group of the RT 3 compounds one of the most known is RNi 3 . Partially replacing of Ni atoms by other 3d elements leads to changes in magnetic properties correlated with the electronic structure [1][2][3][4][5][6][7]. One of previously studied series is Gd(Ni 1¡x T x q 3 , where T = Fe or Co [5,[8][9][10][11].…”

The low-field magnetic properties of polycrystalline Gd(Ni1¡xTxq3 (T = Fe, Co) intermetallic compounds are presented. The whole system crystallizes in the rhombohedral PuNi3 type of crystal structure. The composition dependence of the Curie temperature TCpxq is associated with the change in the number of 3d electrons. Moreover, the field cooled and zero field cooled (FC-ZFC) curves at low applied magnetic field are related to the anisotropy of T element. The saturation magnetic moment MSpxq upon doping was estimated based on the hysteresis loops M pHq.
