Magnetic remanence of Josephson junction arrays
In this work we study the magnetic remanence exhibited by Josephson junction arrays in response to an excitation with an AC magnetic field. The effect, predicted by numerical simulations to occur in a range of temperatures, is clearly seen in our tridimensional disordered arrays. We also discuss the influence of the critical current distribution on the temperature interval within which the arra...
متن کاملSynthesis of Magnetic Remanence Correlation , Leg 155
Conventional magnetic stratigraphy was not possible due to the young age (<780 ka) of the recovered sediments. Taking advantage of the exceptionally high sedimentation rates, however, we were able to successfully adopt several other less-utilized magnetostratigraphic techniques. Foremost among these was the identification of short periods of anomalous geomagnetic polarity (i.e., events and excu...
متن کاملThermal synthesis of Hematite nanoparticles: Structural, magnetic and morphological characterizations
Hematite (α-Fe2O3) nanoparticle was synthesized using organometallic compound - ferrocene carboxaldehyde through solventless solid state thermal decomposition technique. The crystal structure, magnetic and morphological properties of the decomposed material were studied using powder X-ray diffraction (XRD), superconducting quantum interference device (SQUID) magnetometry, ...
متن کاملMagnetic properties of hematite with large coercivity
The magnetic properties of hematite powders produced by a solid state nucleation-and-growth process are studied as a function of temperature T and applied field H. Independently of the temperature, there exists a soft magnetic contribution that is assigned to the canting of spins at the superficial shell of each particle and is not affected by the Morin transition. At 220 < T < TM a magnetic co...
متن کاملInfluence of demagnetization in remanence curves of magnetic thin films
Remanent magnetization curves of perpendicular magnetic thin films are simulated and measured. The simulations are used to investigate the theoretical influence of the strong demagnetizing field present in these films. Conclusions are drawn from this on how remanence curves should be measured and how they should be c0rrecte.d for the demagnetizing influence. The experimental part consists of me...
