Microwave Resonance Absorption in Gadolinium Metal

The microwave resonance absorption in gadolinium metal has been measured at 9000 and 24 000 Mc/sec. The $g$ value in the paramagnetic region is found to be 1.95±0.03. In the ferromagnetic region extreme line breadth prevents accurate determination of the $g$ value. Calculations neglecting effects of line breadth give a ferromagnetic $g$ value of 1.94.
