The fuorides K3Fe5F15 and K3Cr2Fe3F15 are known as multiferroic materials. We reported the detection of a magnetic memory effect in these materials and its dependence on temperature and aging time. We succeeded in writing, reading, and deleting 3-bits digital information in these systems. These results show that in addition to their already known magneto-electric multiferroic properties, K3Fe5F15 and K3Cr2Fe3F15 also possess a new functionality: they can be used as materials for a thermal memory cell.

14N nuclear quadrupole resonance (14 N NQR) of several commercially available paracetamol tablets was measured. The spectra of two polymorphs are presented. The linewidths of the correspondent [sup]14N NQR lines in all the measured samples containing the room-temperature stable monoclinic polymorph were noticeably different. We proved experimentally that the linewidth differences are the consequence of different compacting pressure in the production of tablets.

In the example of detection of pollution sources under the surface both on land and under water, we described the application of the electromagnetic multisensory robotic system, in which we integrated radar imaging, electromagnetic induction sensor, camera and magnetometers. The system also allows for expansion with the laser LIDAR and Terahertz sensor.

In the example of study of insulating polymer foams we demonstrated an application of the Terahertz spectroscopy and imaging. THz imaging achieves a better spatial resolution than radar imaging due to shorter wavelengths, however it is less robust for the field applications. We therefore used the THz spectroscopy and imaging as a laboratory method for collecting additional structural information, which is not achievable with radar imaging at lower frequencies.

In the frame of bilateral project Slovenia-Serbia we studied magnetic and structural properties of CoFe2O4 nanoparticles suspended in an organic liquid. Nanoparticles had a narrow size distribution of average particle size 5.9 ± 1.0 nm. Relatively high blocking temperature at approximately 160 K enable us to use the CoFe2O4 nanoparticles for a thermal memory cell at temperatures above 100 K. On the other hand, the nanoparticles are superparamagnetic at room temperature makes them very suitable for various biomedical applications.
