Devices employing surface acoustic waves (SAWs) are of major interest in sensor applications, due to their ease of manufacturing, sensitivity, small size, and wireless interrogation. This study shows that the response of a magnetic SAW device is much more complex than as is often reported, and that a detailed understanding of its magnetic properties is essential to controlling the magnetoacoustic response. For example, sensing can be extended to out-of-plane fields, beyond the traditional in-plane measurements.
