Giant electromechanical response of ferroelectric relaxors of the PMN - PT type has opened new possibilities to convert electrical energy into mechanical work for the application in ultrasound and medical technology, as well as telecommunications.

We have succsessfully thermally written one byte of eight bits of digital information (a 1 and a 0), so that the Taylor-phase crystal represents a thermal memory cell. The discovery represents the introduction of a new kind of a memory element, where digital information is stored by pure themperature manipulation in the absence of any external static electrical or magnetic field or electromagnetic radiation.

In the context of physics of quasicrystals, it was commonly believed that semiconducting and even insulating quasicrystals could exist. We have also shown that the insulating behaviour appears only in porous polycrystalline samples and not in the high-quality monocrystals.

This work reports the discovery of the first system with the lack of long range order, in which the magnetoelectric effect has been observed. The model system is the site- and charge disordered solid solution 0.8Pb(Fe1/2Nb1/2)O3-0.2Pb(Mg1/2W1/2)O3 (0.8 PFN–0.2 PMW) ceramics, which was shown to be a magnetoelectric relaxor exhibiting a magnetoelectric effect. The results demonstrate that both the electric and the magnetic nanodomains exist in this system and that the magnetoelectric effect is due to the coupling between the local polarizations and magnetizations without any long range order.

The above paper reports polarization-enhanced method of NQR detection of TNT explosive and its realization towards amplification of the 14N NQR signal through coupling to the hydrogen in the TNT molecules. Under specific conditions, the strong nuclear spin magnetization of 1H can be transffered to the system of 14N spins, which enchances the detectable 14N signal by a factor up to 100x. Employing this technique, 1g of TNT could be detected within a few seconds. The method is immediately applicable to portable landmine detectors.
