Paramagnetic Resonance Absorption in Copper Formate

Abstract

Paramagnetic resonance in single crystals of copper formate tetrahydrate and its dehydrate was investigated at room temperature with microwaves of λ=11∼5 mm. Either crystal has only one absorption peak at any direction of static magnetic field. The line width of the tetrahydrate is 400 oer. in order and that of dehydrate is 200 oer. The shape of these lines is Lorentzian.
