TL;DR: In this article, a two-sublattice metamagnet with thermal dependence of the magnetic anisotropy parameter but with constant parameter of the inter-sub lattice isotropic exchange coupling is investigated in classical approximation.
Abstract: The collinear, two-sublattice metamagnet with thermal dependence of the magnetic anisotropy parameter but with constant parameter of the inter-sublattice isotropic exchange coupling is investigated in classical approximation. Using Pal's form of the phenomenological free energy, the magnetization curves for both mT(h) and mh(T) processes are derived. The possibility of occurrence of the spontaneous metamagnetism is demonstrated and its criterion is derived. Moreover, the stable oblique phase is studied, exhibiting new interesting abrupt magnetic transitions on its phase boundaries. Some rules for the accompanying volume jumps are established.

TL;DR: In this paper, a microscopic theory is employed to investigate the spin wave spectra in metamagnetic materials that consist of ferromagnetically ordered layers, with the intralayer ferromagnetic exchange interactions being much stronger than the weak antiferromagnetic interaction between adjacent layers.

TL;DR: In this article, the exchange field coefficient n(RCo) was derived from the Curie temperature and follows the general trend of rare-earth-3d intermetallic interaction exchange.
Abstract: The Nd1-xYxCo9.5V2.5 compounds with x = 0-1 crystallize in the tetragonal ThMn12 structure. The lattice parameters a, c and the cell volume V decrease with increasing Y content. The Curie temperature increases for x less than or equal to 0.2, then decreases with increase of the Y content. The exchange field coefficient n(RCo) was derived from the Curie temperature and follows the general trend of rare-earth-3d intermetallic interaction exchange. The high field saturation magnetization decreases with increase of the Y content. A domain wall pinning phenomenon was observed in all of the compounds and the substitution of Y for Nd makes this phenomenon less obvious. High field measurements of the magnetization show a field induced metamagnetic transition in each compound and the critical field H-crit(H) decreases with increase of the Y content.
