The linear magneto-optical effect in the incommensurate magnetic phase of the known antiferromagnetic magnetolelectric LiNiPO4 was revealed which evidences the loss of the crystal symmetry at the transition from a paramagnetic to a modulated antiferromagnetic state of symmetry relative to a combined space-time inversion operation.
It has been shown experimentally that in double-layer microresonator photonic crystals based on a bismuth-substituted iron-yttrium garnet a record increase in the magneto-optical Faraday effect is observed, this material demonstrating and have well-defined advantages over other types of magnetic photonic crystal.
The low-temperature properties of microresonator magnetic photonic crystals, the magnetic-active layer of which has a magnetic compensation temperature, have been investigated for the first time, and it has been shown that under strong temperature changes of magnetoopic properties of defect layers, the resonance wavelength does not change within thousandths parts. The results can be used when creating magnetic photonic crystals with temperature-sensitive properties.
Anomalies of magnetoresistive and magneto-optical properties of ferro-magnetic/normal metal [Co/Cu]n multilayer nanofilms observed at certain thicknesses of layers of normal metal have been detected experimentally and it is shown that they are accompanied by nanostructuring of ferromagnetic metal layers caused by the indirect influence of spatial electronic quantization in copper layers on the structure of cobalt layers.
For the first time, the behavior of hydrogen bonds in Co-containing double layered hydroxides
