Exchange interactions in Gd1−xCexMn2Ge2 compounds

Analysis on three-sublattice model of magnetic properties in rare-earth iron garnets under high magnetic fields

“…Nevertheless, it is also found that some models show little agreement with experimental observations. Here, a fact should be accepted, i.e., the molecular field theory of Néel has been shown very successful to explain the magnetic properties of rare-earth garnets or some other magnetic compounds [10,11]. Whereas, we also notice that, when using the molecular field theory, the determination of the molecular field coefficients is much more difficult, and shows great importance to the theoretical analyses on the magnetic properties of REIG [12].…”

High field magnetic anisotropy in praseodymium gallium garnet at low temperatures

“…M is the magnetization, v is the coefficient related to exchange effective field, is the magnetic susceptibility, and then, Á = v [12,13].…”

Extension of the molecular-field theory on the magnetic behaviors in paramagnetic Dy3Ga5O12

“…That is, with a special consideration of the exchange interaction in paramagnetic media transformed from the antiferromagnetism, the molecular-field theory is further extended to study the magnetic properties of these media around the transition temperatures. At the same time, as is known, the exchange interaction of the paramagnetic state in rareearth-transition metal compounds can be wonderfully described by the two-sublattice molecular-field model [16,17]. Consequently, in our calculations, it is assumed that two magnetic sublattices exist in DyGaG, and the magnetizations M A and M B are discussed.…”
