Identification of symmetry, structure and defects of dopant Mn(II) ions in Zn(C3H3O4)2(H2O)2 by single crystal EPR technique

Theoretical studies of the g factors and local structures of the Ni3+ centers in Na2Zn(SO4)2·4H2O and K2Zn(SO4)2·6H2O crystals

“…As is known, electron paramagnetic resonance (EPR) technique can provide useful information about the local structures and the dynamics for these TM impurities in the host lattices and enable to identify the site symmetries and electric fields around the dopants in the hosts. [11,12] Since 1950, the properties of Cu 2+ -doped Tutton salts have been widely studied by means of the EPR technique. [13] Although much attention has been paid on the EPR studies for Tutton salts doped with Cu 2+ , Mn 2+ , and VO 2+ impurities, few researches were carried out for Ni 3+ in Tutton salts.…”

The EPR study of Mn2+ ion doped DADT single crystal produced under high pressure and temperature

“…EPR of Mn 2+ impurity has been widely studied in variety of single crystals [1][2][3][4][5][6][7][8][9] due to sensitivity of its spin-spin dipolar splitting values to small structural distortions in the lattice [10,11] and high numbers of studies were reported on impurities doped into diamagnetic host lattices under normal atmospheric conditions and room temperatures, e.g. see [12][13][14][15]9].…”

“…see [12][13][14][15]9]. Diammonium D-tartrate or tartaric acid-di-ammonium salt, (NH 4 ) 2 C 4 H 2 O 6 , (DADT hereafter), is a biochemical substance and is widely used as food additives, as antioxidant, in cell culture solutions [25,26], for dissolving certain metal salts which are poorly soluble in water by forming complexes with them -except Mn 2+ ion -and in EPR dosimetry applications [27][28][29][30][31].…”

Effect of paramagnetic doping on an inorganic polymer triaquadipotassiumbis(malonato)zincate: spectroscopic investigation

“…Electron paramagnetic resonance (EPR) of Mn(II) has been investigated widely in octahedral, tetrahedral and cubic environments (1)(2)(3)(4)(5)(6)(7)(8)(9), since Mn(II), being a d 5 ion, is sensitive to distortions from perfect octahedral or tetrahedral symmetries. Hence, it is used as a paramagnetic impurity to identify distortions, phase transitions, structural and dynamic aspects of crystalline states, etc.…”
