Magnetoresistance studies of metallic granular and ceramic thin films for microsensor applications
Thin films of granular metal and manganites ceramic were fabricated using RF magnetron sputtering and pulsed laser deposition techniques. The GMR effect is highly influenced by the shape, size and distribution of the magnetic entities. The highest GMR value of 7.6% for Ag87.0Fe9.5Co3.5 granular film...

| description | Thin films of granular metal and manganites ceramic were fabricated using RF magnetron sputtering and pulsed laser deposition techniques. The GMR effect is highly influenced by the shape, size and distribution of the magnetic entities. The highest GMR value of 7.6% for Ag87.0Fe9.5Co3.5 granular film measured at 1 Tesla at room temperature had been obtained. In the polycrystalline manganites system, low-field magnetoresistance (LFMR) had been observed due to the grain boundaries. LFMR of 4.3% and 6.2% measured at 0.1 Tesla at room temperature have been observed for both La-Sr-Mn-O and La-Ba-Mn-O samples. For the La-Sr-Mn-O film, LFMR ratio of 4.5% has been observed. This value meets the requirement as sensor element and it is currently used in many applications such as head sensing in hard disk. |
