  Nanospintronic and related research often requires the application of fast
rising magnetic field pulses in the plane of the studied planar structure. We
have designed and fabricated sub-milimeter-sized coils capable of delivering
pulses of the magnetic field up to ~ 500 Oe in the plane of the sample with the
rise time of order of 10 ns. The placement of the sample above the coil allows
for an easy access to its surface with manipulators or light beams for, e.g.,
Kerr microscopy. We use the fabricated coil to drive magnetic domain walls in 1
${\mu}$ m wide permalloy wires and measure magnetic domain wall velocity as a
function of the applied magnetic field.
