“…2(c). This behavior suggests a spin-flop transition, which was first experimentally observed in CuCl 2 • H 2 O single crystals [15], and has since also been observed in many other systems with magnetocrystalline anisotropy [16,17,18,19,20,21,22,23,24]. In a spin-flop transition with weak magnetocrystalline anisotropy, when a magnetic field is applied parallel to the magnetic easy axis of a material and exceeds a critical value H SF , the simple antiferromagnetic spins suddenly rotate into the spin-flop state where the spins try to align perpendicular to the magnetic field, and this results in a net moment along the easy axis [25].…”

“…The wolframite-type MWO 4 compounds, isostructural to the Mn 1– x Fe x WO 4 tungsten ore, form an interesting class of bimetallic oxides for their properties such as magnetic for M = Fe, Co, and Ni − and even multiferroic in the case of the hubnerite MnWO 4 . More recently, the supercapacitor properties of nanocrystalline ferberite FeWO 4 have been demonstrated and interpreted theoretically, together with previously reported electrode materials , and photocatalytic and photoluminescence properties. , On the one hand, magnetism is dominated by partially filled 3d orbitals of the divalent M cations, whereas, on the other hand, electrochemical activity is believed to be related to the Fe 3+ /Fe 2+ redox couple existing in Fe-deficient Fe 1−δ WO 4 compounds; this activity is exacerbated by the surface effect in the nanocrystalline form .…”

Synthetic crystals of the ferberite FeWO4 have been grown by the chemical transport reaction starting from a polycrystalline sample of this phase. Magnetic susceptibility measurements showed an antiferromagnetic Néel temperature of T N = 75 K. The anisotropy in the magnetic susceptibility can be ascribed to the magnetocrystalline anisotropy of the Fe2+ ion, the oxidation state of which was confirmed by X-ray absorption spectroscopy. While X-ray photoemission analysis indicated that all W ions are in the expected 6+ charge state, the dielectric permittivity of the FeWO4 crystals was found to be leaky, hindering changes at T N to be detected. Subsequent thermoelectric power measurements suggested the presence of about 1.5% Fe3+. X-ray diffraction experiments confirmed the basic crystal structure of the wolframite type and revealed some structural disorder in the 1% range. Transmission electron microscopy allowed us to unveil the occurrence of stacking faults attributed to the similarity of the atomic environment of the Fe and W species.

This paper reports an experimental high-pressure study of natural mineral ferberite (FeWO 4 ) up to 20 GPa using diamond-anvil cells. First-principles calculations have been used to support and complement the results of the experimental techniques. X-ray diffraction patterns show that FeWO 4 crystallizes in the wolframite structure at ambient pressure and is stable over a wide pressure range, as is the case for other wolframite AWO 4 (A = Mg, Mn, Co, Ni, Zn, or Cd) compounds. No structural phase transitions were observed for FeWO 4 , in the pressure range investigated. The bulk modulus (B 0 = 136(3) GPa) obtained from the equation of state is very close to the recently reported value for CoWO 4 (131(3) GPa). According to our optical absorption measurements, FeWO 4 has an indirect band gap that decreases from 2.00(5) eV at ambient pressure to 1.56(5) eV at 16 GPa. First-principles simulations yield three infrared-active phonons, which soften with pressure, in contrast to the Raman-active phonons. These results agree with Raman spectroscopy experiments on FeWO 4 and are similar to those previously reported for MgWO 4 . Our results on FeWO 4 are also compared to previous results on other wolframite-type compounds.
