Magnetic Dynamics in a Nickel Films with Toothed Stripe Structure under the Impact of Acoustic Pulses

The authors study conditions for the magnetization reorientation of nickel nanofilms with a toothed stripe structure when acoustic pulses of Gaussian shape pass through them. The behavior of such films in a constant magnetic field is studied and hysteresis loops are constructed, depending on the angle of the field’s application. Modeling is done using the MuMax3 software package. Results can be used in developing advanced compact and energy-efficient magnetic recording devices.
