Abstract: | Paramagnetic resonance and magnetic measurements were performed on powdered samples of GdGa2. The magnetic data indicated ferrimagnetic behavior with . Above 250° K the susceptibility obeys the Curie-Weiss law which corresponds to an effective moment of 7.95 Bohr magnetons. Over the range from 190 to 300°K the data obey a Néel type law, , which is indicative of ferrimagnetic order. The resonance measurements were performed at 9.013 gHz at 247, 296, and 349°K. The spectra were analyzed with a computerized curve-fitting technique that involves a linear combination of Lorentzian absorption and dispersion susceptibility components. Following demagnetization corrections, the g-factor was found to be 1.9832 while the half-power, half-linewidth was 592.7 Oersteds. |
