9. In the graphic below we have two types of materials X and Y: i) a & b refer to material "X" in the absence of an external magnetic field and in the presence of magnetic field respectively. "c" refers to material "Y" with different domains having different orientations of electron spin and "d" refers to material "Y" under the influence of an external magnetic field. Identify whether (X or Y) is paramagnetic or ferromagnetic or neither. ii) ii) X: (a) (b) AAA. TTTTT Y: (c) (d)
