With the existing GPR systems it is possible to detect the structural irregularities several meters in the depth. Unfortunately, the image reconstruction is slow and not reliable. It takes several minutes and the obtained image does not allow judging what type of object is under the earth surface. We therefore improved the time for image calculation using Stolt migration to less than fifteen seconds and improved the antenna array to extend the frequency range to 30 MHz - 5 GHz.

It was shown that the 14N NQR successfully discriminate between different forms of piroxicam. 14N NQR spectroscopy demonstrated that it is successful in complemental studies of solid forms of pharmaceutical substances.

Muon spin relaxation has been employed to investigate the local magnetic properties of multiferroics K3Fe5F15, K3Cr2Fe3F15, in K3Cu3Fe2F15. In all investigated systems muon spin relaxation revealed a linear F-µ+-F “hydrogenlike” bonded complex. Two consecutive magnetic transitions were found in all systems, in agreement with the magnetic susceptibility measurements. The muon spin relaxation results further suggest that the system is inhomogeneous below TN with magnetically ordered clusters being embedded into a disordered matrix.

Sulfate of copper(II) is known for millennia. The related AuSO4 has been known for a decade, while very recently within the collaboration with Polish researchers we finally succeeded to synthesis the related sulfate of silver(II). The AgSO4 shows many different chemical and physical properties like the related copper and gold compounds. The chains of Ag(II) ions compose a 3-dimensional network which is reflected in unusually and interesting magnetic properties: a very strong intrachain antiferromagnetic interaction between the Au(II) ions.

We present a concept of a new kind of memory element, a thermal memory cell, where a byte of digital information is stored into the storage medium by pure thermal manipulation. Thermal inscription of information employs a specific temperature-time profile that involves continuous cooling and isothermal waiting time periods. Our storage media are magnetically frustrated solids. We succeeded to thermally write arbitrary ASCII code. Besides for data storage, the concept may be employed for secure data transfer and for retrieving cosmological information from extraterrestrial dust particles.
