Abstract

We report the results of wide temperature range material characterization and propagation studies on ion-implanted and annealed (Y1.9Bi0.5Ca0.60.6)(Fe4.4Si0.6)O12Effective uniaxial anisotropy field Hkdecreases by less than a factor of 1.5 in going from -60C to +140 C compared with a factor of 8 for typical Lu-Sm garnets. Coercivity is less than 0.50e at -60C, and decreases monotonically to 0.14 Oe at 140C. Bubble propagation studies with 4μm-period ion-implanted propagation patterns and 40 Oe, 100 kHz drive field show propagation on the best type of tracks from -130 to 160C, with a bias field operating range greater than 30 Oe.
