Electron Spin Resonance in Single Crystals of Anhydrous Copper Sulfate

摘要: The magnetic resonance of synthetic anhydrous copper sulfate has been investigated at 23.3 GHz temperatures between 77°K and 4.1°K. In the paramagnetic region, observed consists two lines. One these is relatively narrow remains essentially fixed even down to second line unusually broad its behavior indicates that it due ions in crystal. g values corresponding linewidths have measured for 77°K. As temperature drops Neel point, this increases width, then shifts, disappears rather rapidly, indicating associated with antiferromagnetic phase.
