Abstract

At a pulsed muon source, a radio-frequency pulse timed to rotate the implanted muon spin polarization by 90° can be used to completely remove the frequency limitations imposed on conventional spin rotation experiments by the finite muon pulse width. This contribution presents two applications of the method, where controlling the excitation bandwidth of the radio-frequency pulse provides unique information. In the first case, an intense 90° pulse is used for broadband excitation of a paramagnetic system, while in the second case a low power pulse applied in the presence of a field gradient excites a limited frequency band leading to spatial localization of the muon signal.
