In BCCD the EPR probes Mn 2+ , VO 2+ , and as an irradiation centre the radical N(CH 3 ) 3 monitor the incommensurate modulation. Interesting results on the influence of defects on the order parameter were obtained using Mn 2+ taking into account the

By a combination of $X$-band and $Q$-band ESR investigations it was possible to distinguish between effects of first and second order in the critical behavior, which are influenced in different ways by the dynamics of the order-parameter fluctuations

For the interpretation of the EPR lineshape of incommensurate phases there exist many theoretical models. We suppose a simple physical model to interpret the lineshape of the Mn 2+ EPR spectrum of the first incommensurate phase of betaine calcium chl

EPR investigations on Mn 2+ -doped calcium chloride dihydrate monitor the rich variety of commensurate and incommensurate phases. The line shape in the first incommensurate phase is interpreted by assuming a superposition of one line with two edge si

EPR investigations on Mn2+ doped betaine calciumchloride dihydrate show that Mn2+ incorporated at Ca2+ sites is a good indicator for the modulated phases of BCCD. At low temperatures the existence of a nonmodulated phase with low symmetry was confirm

Pulse sequences with multiple lengths of echo spacings are used in oilfield NMR logging for diffusion‐based NMR applications such as rock and fluid characterization. One specific implementation is the so‐called diffusion editing sequence comprisi

EPR studies show axial Cr3+ centres in Cr-doped ferroelectric PbTiO3 ceramic after heat treatment in hydrogen atmosphere. The fine-structure splitting at room temperature was interpreted on the basis of the Newman superposition model. The temperature

EPR spectra of Mn2+, Mn4+, Cr3+, Gd3+ ions in PbTi03, ceramics substituted for Ti4 + and Pb2+, resp. show different temperature dependences of their fine structure. It is revealed that near the ferroelectric transition the motion of Cr3+ and Mn2+ is
