The coupling of spin and orbital angular momenta underlies the magnetic anisotropy properties of ferromagnets. Strong anisotropy allows for permanent, stable storage but also requires stronger ...
The electronic heart of a hard disk drive is the read-channel integrated circuit (IC). Over the years, read-channel designers have delivered dramatic improvements in signal-to-noise ratio (SNR), ...
Higher - The gradients of two perpendicular lines will always multiply to make –1. Make sure you are familiar with finding the equation of a line and calculating gradient to understand equations of ...
