摘要：
The resonant frequency shifts of magnetically capped oscillators under the applied magnetic field were investigated by using magnetic resonance force microscopy (MRFM) techniques. For low fields, magnetic moments were nearly perpendicular to the applied field while frequency decreased with increasing field value. At high field value, moments were nearly aligned with the filed whereas frequency increased with increasing field.
