Magnetic properties of multiferroic ▫${\rm K_3Cr_2Fe_3F_{15}}$▫Blinc, Robert ...The local electronic and structural as well as the macroscopic magnetic properties of ▫${\rm K_3Cr_2Fe_3F_{15}}$▫ have been studied between room temperature and 4 K. The system has been found to be ... isostructural with ferroelectric and weakly ferrimagnetic ▫${\rm K_3Fe_5F_{15}}$▫ above the ferroelectric transition temperature ▫$T_c$▫. The X-band and 216 GHz Cr▫$^{3+}$▫ electron paramagnetic resonance (EPR) spectra as well as the magnetic susceptibility and Mössbauer data show the existence of two magnetic relaxor type transitions around 37 and 17 K. ▫The $^{39}$▫K math magic angle sample spinning NMR, EPR, and the Mössbauer data further demonstrate the existence of two nonequivalent Fe, Cr, and K sites in the unit cell as well as the presence of rapid exchange at higher temperatures. The observation of the Fe▫$^{2+}$▫ EPR and Mössbauer spectra shows that the Fe▫$^{2+}$▫ ion is in a high spin state.Source: Journal of applied physics. - ISSN 0021-8979 (Vol. 107, no. 4, 2010, str. 043511-1-043511-5)Type of material - article, component partPublish date - 2010Language - englishCOBISS.SI-ID - 23425063
