Iron has an easy axis in the [100] direction. If the flakes are dropped onto the flat surface of a specimen holder, a) Draw the -2 x-ray diffraction pattern expected.</p><p> b) Draw the -scan of the (110) x-ray diffraction peak expected.</p><p>If a magnetic field is now applied in the plane of the deposit, c) Draw the -2 x-ray diffraction pattern expected.</p><p> d) Draw the -scan of the (110) x-ray diffraction peak expected.</p><p>2. The measured -2 and -scans for two platinum (F cubic) thin films are shown below. The first set of plots is for a platinum film grown on a silicon single crystal and the second set is for a platinum film grown on a SrTiO3 single crystal. 2000PlatinumPt 102004f-ScanPlatinumf ә 0° along ofon Si on Platinum[001]Si Si(100) (100) 311 Peak Intensity10001500 Intensity (arbitrary1023 units) (arbitrary units) 5000 PtSi 111101 400 1020302q 4050(degrees)607080090f 180(degrees)3270360 200000Platinum3100Pt 33 200(100) 4200f-ScanPlatinumf ә on0°3 [001](100)SrTiO along of SrTiOon420 SrTiO Platinum Peak Intensity100000150000SrTiOSrTiO (arbitrary3 103 units) 500000102030405060IntensitySrTiO70300801012090180270360 (arbitrary units) a) Which film(s)2q is(are) epitaxial?(degrees) Why? f (degrees)</p><p> b) For the epitaxial film(s) specify the orientation relationship.
