Magnetic Properties · Magnetic Properties of Non-Metallic Inorganic Compounds Based on Transition Elements · Garnets

Volume III/27 covers the magnetic properties of inorganic compounds based on transition elements. It can therefore be considered as a supplement to volumes III/4 and III/12 "Magnetic and other properties of magnetic oxides and related compounds" which appeared in 1970 and in the period 1978 - 1982 respectively. In a way this volume also forms a counterpart to volume III/19, in which the magnetic properties of met- als, alloys and metallic compounds are compiled. The first subvolume, III/27a, which appeared in late 1988, deals with the magnetic properties of pnictides and chalcogenides which contain 3d elements. Subvolume III/27d treats oxy-spinels. In the present subvolume III/27e oxidic compounds with the garnet structure are considered; they include both iron and non-iron substances. Physical and chemical properties which are of interest in connection with the magnetism of the garnets, have been given the necessary attention. Lists of iron and non-iron garnets help the user of this subvolume to find the substance he is interested in, and which are to be found in various parts of volumes III/4, III/12 and III/27. 4.1.1.2 List of frequently used symbols and abbreviations....Pages 1-4 4.1.2.1.1 Saturation magnetization and Curie temperature....Pages 4-18 4.1.2.1.2 Molecular-field- and exchange constants....Pages 18-19 4.1.2.1.3 Magnetic moments of the rare earth ions....Pages 20-21 4.1.2.2 Magnetic phase transitions....Pages 21-22 4.1.2.2.1 Spontaneous spin-reorientational transitions....Pages 22-23 4.1.2.2.2 Field induced transitions....Pages 23-24 4.1.2.3.1 Cubic anisotropy....Pages 25-30 4.1.2.3.2 Non-cubic anisotropy....Pages 31-39 4.1.2.4.1 Resonance field....Pages 39-40 4.1.2.4.2 FMR line width....Pages 40-43 4.1.2.4.3 g-factor....Pages 43-44 4.1.2.5.1 Spin waves and magnetostatic modes....Pages 45-46 4.1.2.5.2 Non-linear effects and relaxation....Pages 46-49 4.1.2.6 Nuclear magnetic resonance (NMR)....Pages 49-51 4.1.2.7 Mössbauer spectroscopy....Pages 51-53 4.1.2.8.1 Static properties....Pages 53-57 4.1.2.8.2 Dynamic properties....Pages 58-60 4.1.3.1 Magnetostriction....Pages 60-62 4.1.4 Elastic properties....Pages 63-64 4.1.5 Optical and magnetooptical properties....Pages 64-65 4.1.5.1.1 Absorption of light....Pages 65-73 4.1.5.1.2 Reflection of light....Pages 73-74 4.1.5.1.3 Refractive index....Pages 75-76 Figs. 177 - 201, Table 18....Pages 77-86 Figs. 202 - 215, Table 19....Pages 87-93 4.1.5.2.2 Magnetic circular dichroism (MCD)....Pages 93-99 4.1.5.2.3 Kerr effects....Pages 100-101 4.1.5.2.4 Magnetic linear birefringence (MLB) and nonmagnetic linear birefringence....Pages 102-103 4.1.5.2.5 Magnetic linear dichroism (MLD)....Pages 103-104 4.1.5.3 Photoinduced effects....Pages 104-106 4.1.6 Thermal properties....Pages 106-107 4.1.7.1 Electrical conductivity....Pages 107-109 4.1.7.2 Magnetoresistance and magnetoelectric effect....Pages 110-110 4.1.8 Crystal structure....Pages 111-113 4.1.9 References for 4.1....Pages 113-123 4.1.10 List of iron garnets in Vols. 4A, 4B, 12A and 27E....Pages 123-135 4.2.1.2 List of frequently used symbols and abbreviation....Pages 136-140 4.2.2.1 Rare earth garnets....Pages 140-142 4.2.2.2 3d-ion garnets....Pages 143-148 4.2.3 Magnetization and magnetic structure....Pages 148-148 4.2.3.1 Magnetic moments and magnetic anisotropies of terbium, dysprosium and holmium aluminum garnets....Pages 149-150 4.2.3.2 Magnetic moments of rare earth gallium garnets....Pages 151-152 4.2.3.3 Magnetic neutron scattering in dysprosium aluminum garnets....Pages 153-155 4.2.3.4 Magnetic neutron scattering in terbium, holmium and dysprosium gallium garnets....Pages 156-156 4.2.3.5 Magnetization and magnetic phase transitions in manganese germanium garnets....Pages 157-159 4.2.3.6 Garnets with several 3d-ions....Pages 160-161 4.2.4.1 Electron paramagnetic resonance of paramagnetic metal ions in diamagnetic garnets....Pages 162-164 4.2.4.2 Electron paramagnetic resonance of rare earth ions in diamagnetic garnets....Pages 164-165 4.2.4.3 Electron paramagnetic resonance of impurities in paramagnetic garnets....Pages 166-166 4.2.4.5 Antiferromagnetic resonance....Pages 167-168 4.2.5.1 Crystal-field parameters....Pages 169-170 4.2.5.2 Optical spectra and index of refraction....Pages 171-185 4.2.5.3 Information on colour centres....Pages 186-189 4.2.5.4 Further references for results from optical measurements....Pages 190-196 4.2.5.5 Magnetooptical properties....Pages 197-201 4.2.6 Mössbauer spectroscopy....Pages 202-204 4.2.7 Electron spin-lattice relaxation of paramagnetic ions in garnets....Pages 205-206 4.2.8.1 Heat capacity....Pages 207-215 4.2.8.2 Derived thermodynamic functions....Pages 215-218 4.2.8.3 Debye temperature....Pages 218-219 4.2.8.4 Thermal expansion....Pages 219-221 4.2.8.5 Kapitza conductance....Pages 222-222 4.2.8.6 Thermal conductivity....Pages 223-226 4.2.8.7 Ultrasound attenuation....Pages 227-230 4.2.9.1 Elastic and photoelastic constants at room temperature....Pages 230-231 4.2.9.2 Temperature dependences....Pages 231-232 4.2.10.1 Magnetostriction of rare earth garnets....Pages 232-235 4.2.10.2 Magnetostriction of antiferromagnetic garnets with 3d-ions....Pages 235-237 4.2.11 Electrical properties....Pages 237-237 4.2.11.1 Electrical conductivity and thermoelectric power....Pages 238-241 4.2.11.2 Photoconductivity....Pages 242-242 4.2.12 References for 4.2....Pages 243-253 4.2.13 List of non-iron garnets in Vols. 4B, 12A and 27E....Pages 253-263 In subvolume III/27C2 magnetic and related properties of binary actinide oxides have been compiled.
