| Research Abstract |
The granular films consisting of a ful-Heusler CFAS alloy and Al2O3 exhibited a large MR ratio of about 18% at room temperature. This value is the largest value ever reported for magnetic metal-insulator granular films. It was suggested that the large MR ratio was obtained owing to the existence of granules with L21 or B2 phases, which exhibit high spin polarization. This result showed the possibility of the application of the half-metal to the granular films.
