摘要: A method for driving a spin valve element, including passing driving current through the spin valve element to generate an oscillation signal, and performing amplitude modulation of the driving current at a frequency lower than the oscillation frequency of oscillation signals. This amplitude modulation can be ON-OFF modulation, and the interval ton in the conducting state of the ON-OFF modulation is made to satisfy the relation ton
