Thickness dependent magnetization dynamics of perpendicular anisotropy Co/Pd multilayer films

Magnetic states in low-pinning high-anisotropy material nanostructures suitable for dynamic imaging

“…With these properties, our material is comparable to typical Co/Pt or Co/Pd multilayers, [23][24][25][26][27][28] and in contrast to other low-pinning materials such as permalloy, it belongs to the class of high-anisotropy materials.…”

“…These materials have been commonly used in a wide range of experiments 1,3,[18][19][20][21][22] and are very well characterized. [23][24][25][26][27][28][29] Second, the pump-probe scheme relies on a deterministic and elastic response of the magnetic domains and domain walls to drive forces of up to GHz repetition rates. This requires a material with particularly low pinning to provide the high repeatability of the domain wall motion, which is also of key importance for applications.…”

Demagnetizing fields in all-optical switching

“…The sample magnetization was re-initialized between pump pulses with a constant field |B| = 300 G from two water-cooled coils. The relatively strong damping α ≈ 0.1 in Co/Pd [45,46] insures that the magnetization is stable within the 12.5 ns time interval between pulses. This allows measuring transient processes with the same initial and final states.…”

Solid-state synthesis, structural and magnetic properties of CoPd films

“…Multi layer Co/Pd samples have a perpendicular magnetic anisotropy of ~8 × 10 6 erg/cm 3 [4], which is slightly less than in materials with high uniaxial magnetocrys talline anisotropy [5]. Experimental observations revealed that heating to ~400°C does not change the magnetic properties of Co/Pd multilayers.…”
