A non-resonant microwave technique has been employed for the determination of saturation magnetisation (4πMs) andg-factor of pure and Gd-doped single crystal YIG spheres yielding accurate values. It was found that 4πMs=1720–1751 g for undoped and 1595 g for 10% Gd-doped YIG spheres whilegeff=2·00–2·0039. The advantages of this method are simplicity and complete absence of propagation corrections necessary in cavity resonance experiments.
