Consider a thin film given in the figure. The uniaxial crystalline anisotropy along the x axis is K1>0.
Tension (?) is applied along the y-axis: 3(??)/2>K1. Do not worry about the shape anisotropy. (100 pts)
A. If Hx = 0, what is the angle ?? (20 pts)
B. If Hx is increased from zero, find the angle ? after saturation, and find the expression for Hx as a
function of Mx (10 pts/each). Draw a hysteresis loop of Mx along Hx. You must give the expression
for Mr, Hc and the slope of a line if necessary to get a full score (10/each).
C. If, instead, H is along the direction of the tension (y axis), find the angle ? after saturation, and
find the expression for Hy as a function of My (10 pts/each). Draw a hysteresis loop of My along Hy.
You must give the expression for Mr, Hc and the slope of a line if necessary to get a full score
(10/each).
