The tube was continuously rotated round its axis to avoid temperature variations. Excitation of the magnet caused immediate widening of the lines. It thus appears very probable that the period of ...

interactions with external magnetic fields, and relaxation processes. The second portion of the course will discuss basic concepts of image formation, including radiofrequency pulse excitation, ...

as well as various types of magnetic domain walls that connect them. Through an antenna, the group applied radio frequency electric signals to the sample causing an excitation of the spins.

Consider an undamped single degree-of-freedom system experiencing harmonic excitation whose equation of motion (EOM) is given by: Here omega n is known as the natural frequency of response. The ...
