Introduction: To obtain accurate quantitative perfusion data, continuous arterial spin labeling (CASL) requires balancing magnetization transfer (MT) effects in the control and tag experiments. Traditionally, this is done by applying RF pulses in control experiments that are placed at equal distance as the tag pulse to the imaging slice, but distal to the imaging slice of interest and far enoug...

The spin transfer phenomenon provides a new method to manipulate magnetization without applying an external magnetic field and a new playground to study the spin degree of freedom of electrons. Two types of magnetic dynamics excited by the spin transfer torque from a direct current were predicted in 1996: magnetization reversal and steady-state precession. The physics of spin-torque-induced mag...
