Our studies on polynuclear metal complexes with ferromagnetic spin-coupling are described; (1) Tetranuclear Cu(II) and Ni(II) complexes with cubane structure, (2) mixed-metal complexes with imidazolate bridge, and (3) mixed-metal complexes with oxalate or dithiooxalate bridge.

Hetero-metal assemblies, (NBu4=tetra(n-butyl)ammonium ion; ox=oxalate ion; M(II)=Ni(1), Fe(2), Mn(3), Zn(4)) have been synthesized by the use of [Fe(ox)3]3- as the building block. 1 and 2 are ferrimagnets of TN=43 and 28 K, respectively. 3 is an antiferromagnet. 4 shows a paramagnetic behavior.

... Many condensed matter researchers have studied models that describe static magnetism in different materials. One of these models is the well-known mixed-spin Ising model which can describe ferrimagnetic materials [1][2][3]. The interest in the study of ferrimagnetic materials is due to their potential technological applications [4] which is a consequence of this material exhibiting a compensation temperature ( comp ). ...
