We examine double chains of spins 1/2 with Ising-like nearest-neighbor interactions showing magnetic frustrations that we define. The critical temperature of such systems is T c = 0 K like for spin chains (1d systems). We recall the theoretical treat

Diamagnetically diluted iron-gallium borate Fe x Ga 1-x BO3 single crystals have been studied by Antiferromagnetic Resonance (AFMR) at 77 K in the frequency range of 17 to 25 GHz in magnetizing fields up to 10 kOe. Anisotropic energy gap of the low-f

The Dzyaloshinskii-Moriya interaction constant for iron-gallium borate FexGa1-xBO3 single crystals has been calculated on the basis of considering antisymmetric exchange in a pair of nearest-neighbouring magnetic ions. Both numerical and analytical c

Iron borate FeBO 3 is an excellent example of the materials called “transparent magnets” [1], associating room temperature magnetic ordering (weak ferromagnetism) with transmission windows in visible spectral range [2]. The persisting research in

The ε-Fe2O3 nanoparticles in borate glasses co-doped with low concentrations of Fe2O3 and Gd2O3 were investigated with two experimental techniques – visible magnetic circular dichroism (MCD) and electron spin resonance (ESR). The most prominent fe

International audience; The theory of surface magnetism of iron borate, FeBO3, has been extended by taking into consideration a crystal field contribution to the surface magnetic anisotropy energy. For this purpose, a model of distortion of the six-f
